Usually, from oil or natural gas, they are long-chain molecules, each chain having hundreds of thousands of bonds. London, UK: Royal Society of Chemistry, 2006. The word “Polymer” is derived from two Greek words, ‘Poly’ that means many (numerous) and ‘Mer’ which means units. Teflon: Polytetrafluoroethylene (PTFE) is a polymer similar to polyethylene, where hydrogen atoms are substituted by fluorine. Not everything you see here has a polymeric composition. Long-chain polymers often have many kinks in the chains, and these kinks can move and un-kink, causing the material to stretch. What are the most useful polymers in our daily life? Remind students of the study of atoms and basic molecules, and now molecules are going to link together to form a chain; that chain will create our polymer pet. Chemistry, Physical Science. Studadinger received the Nobel Prize in chemistry for his discovery of the chemical structure of natural rubber. The uses of polyethylene are very different from another polymer, poly(vinyl chloride), which is commonly used for water pipes and is able to withstand large amounts of pressure.

Polytetrafluoroethylene (PTFE) (Viton) Viton B … This monomer is similar to polycarbonate in that it cannot be derived from polyethylene's monomer unit. Proteins and DNA are both synthesized from small subunits, called amino acids.Figure 2: Structures and common applications of six polymers.copyrightCopyright © 2012 Cherelle Bishop, Colorado State University, Polymers are formed by a process called polymerization, in which a chemical reaction of reacting monomer molecules forms polymer chains in a variety of complexities. Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. The synthetic polymer Polystyrene is used in cabinets and in packaging. Let’s check its everyday uses. A polymer network is a network in which all polymer chains are interconnected to form a single macroscopic entity by many crosslinks. Figure 4: Polyethylene monomer unit and three other polymer monomers: poly(vinyl chloride), polystyrene and polyacrylamide.copyrightCopyright © 2012 Cherelle Bishop, Colorado State University. Just a few examples of the many, many polymeric materials are shown here. polymer: A material composed of repeating monomer units. Polymers are both found in nature and manufactured in laboratories. Note to teachrs: Refer to Figure 2 in the. The name acid gives us sensory images of – Sourness. Some medical devices are made from polymers. Chain-growth polymerization (or addition polymerization) involves the linking together of molecules incorporating double or triple carbon-carbon bonds. Ahluwalia, V. K. and Mishra, A. Polymer Science: A Textbook. cross-linker: A covalent bond linking two polymeric chains together, sometimes facilitated by a small molecule. ), Polymers are large molecules held together by chemically linked subunits called monomers. A polymer is a chemical term for a material composed of repeating units called monomers. All plants and trees are made of polymers, and we utilize them to make everyday items. Polymers can be made into clear, waterproof films. What are some items made from polymeric materials that you frequently use? Polycarbonate is commonly used in bulletproof glass and headlights, in lenses for headlamps, glasses and sunglasses, as well as in CD, DVD and Blu-Ray discs. For example, needles used for vaccines and IVs use a plastic casing typically made of polyurethane. PVC is used to make medical tubing and blood bags that extend the shelf life of blood and blood products. Another consideration is that many consumer products are made with blended polymeric materials, meaning that more than one polymer is used. Other applications for poly(vinyl chloride) are door frames, waterproof fabric and electrial wire insulation, The only chemical difference between polyethylene and poly(vinyl chloride) is the substitution of one hydrogen atom in polyethylene for a chloride ion in poly(vinyl chloride), as shown in Figure 4. In the form of a film, it shrinks upon heating, allowing it to be used in shrink tunnels.

The next monomer unit, featured in Figure 2, is polycarbonate. Worksheet: Have students complete the Polymer Worksheet. 20. A linear polymer is composed of one molecule after another, hooked together in a long chain called the backbone. Depending on the polymerization reaction conditions, the resulting polymer can be a simple linear chain of linked carbon atoms. Many consumer products are made from polymeric material. Ring stacking can also be observed between chains of polystyrene as with polycarbonate. Materials engineers rely on some polymers for their rigid strength, others for their flexibility, and still others for their resistance to corrosion. Do chemical groups exist in the backbone?). They witness how changes in the degree of cross-linking influence the putty properties. The strengths of a polyethylene plastic bag and a water pipe made from cross-linked polyethylene are very different. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), The act of stretching a polymer forces the polymer chain to align with each other because of the force applied to the material. Communicate scientific and technical information (e.g. What atoms are in the structure? Polymers are a part of our every day life and without them around, this world would be very, very different, if not impossible to live in.

(Answer: The transparent portion of the Nalgene is polycarbonate, but the lids are not made from polycarbonate. How E commerce Marketing Agencies can Promote your Brand in 2019? Polystyrene's monomer unit is similar to polyethylene and poly(vinyl chloride), in which a hydrogen atom in polyethylene monomer is substituted with a six-membered aromatic ring, in the case of polystyrene (see Figure 4). Consumer products also typically use an initial stamp to signify the chemical compositions of the polymer used to create the material. Many of these materials are made from synthetic polymers and were developed in commercial laboratories, but countless other polymer examples are found in nature and in living organisms. Since the 1930s the monomer has been used in co-polymers with elastomeric characteristics [6]. Polymers can be defined as a type of material that is made of long chains or networks with these networks or chains created by repeating units of molecules. Again, polyacrylamide can be derived from polyethylene by substituting a hydrogen atom with an amide functional group. You’ll explore commercial applications of polymers, learn how different plastics are synthesized, and discover how the materials and processes used can affect the product’s recyclability and malleability. The word polymer is derived from the Greek root poly-, meaning many, and mer, meaning part or segment. 94-107. In other words, more cross-linking within a polymeric material results in a more rigid material, whereas less cross-linking results in a more elastic material. Let’s check their uses in our daily life. Another roadblock to recycling some plastics is non-existent demand for the post-recycled materials. CONSTRUCTION &REMODELING. 8), Matter has definite structure that determines characteristic physical and chemical properties Optionally, ask students to include schematics of the polymer chains and describe how certain functional groups interact with other functional groups between different polymer chains. They have many more atoms than a water molecule--from 10,000 to 100,000 atoms per molecule. Do you agree with this alignment? Over-aggressive mixing of slime in the plastic bags can lead to rupture, resulting in a slimy mess. Some consumer products are made polymers, commonly called plastics. Hydrochloric Acid (HCl) Polymers have many applications in various fields as well as in everday life. Do you agree with this alignment?

Then, talk about each item, highlighting its chemical structure. CONCLUSION:-We have tried to give a brief information on polymers .Polymers are everywhere around us and we tried to show a glimpse of polymers applications which are commonly used in our lives like plastics nylon and day to day used commodities. www.teachengineering.org/lessons/view/csu_polymer_lesson01, Search curriculum by Common Core standards, Print lesson and its associated curriculum, Click to view other curriculum aligned to this Performance Expectation. Now, linear polymers do not have to be in a straight, rigid line. Polyethylene, as discussed previously, is used to make plastic shopping bags and many plastic containers, whereas cross-linked polyethylene (abbreviated as PEX) tubing is used in plumbing applications. Monomers can be combined in various repeating patterns to form different types of polymers. Boca Raton, FL: CRC Press, 2002; p. 401. Investigating or designing new systems or structures requires a detailed examination of the properties of different materials, the structures of different components, and connections of components to reveal its function and/or solve a problem. Polymers are used to make electronic components, paint, plastic bottles, sunglass lenses, DVDs and so much more! Polymers are used very widely in the production, distribution, packaging and preparation of food. The inclusion of the aromatic rings can lead to pi-stacking between different polymer chains. We can see the effect of cross-linking on polymeric materials by comparing the strength of polyethylene and cross-linked polyethylene. They are the chemical substances; ranging in pH scale from 0 to 7. Styrene is used for important co-polymers and terpolymers such 6 - Polystyrene is found in many products including: license plate frames, CD cases, Petri dishes, insulation and Styrofoam packing peanuts. Subject Areas: Frequently, this is because some polymeric materials are extremely durable, making recycling of the material costly and time consuming. In chemistry, pi stacking (also called π-π stacking) refers to attractive, non-covalent interactions between aromatic rings. Cups and bags have been made from this material. Figure 6: Common abbreviations for recycling codes and their polymer name and structure.copyrightCopyright © 2011 Cherelle Bishop, Colorado State University. Polymers are a part of our every day life and without them around, this world would be very, very different, if not impossible to live in. Polymers also exist inside the human body. Third Edition. COOKWARES. The clear blue gel plastic on the running shoe is a polyurethane material designed to cushion a runners foot.). synthetic polymer: A polymer was made by humans. Polycarbonate also includes an ester linkage within the polymer back-bone. Acids are common chemicals and can be found everywhere even in our food. During teacher demos, students observe the unique behaviors of thermoplastics. Cellulose, a polysaccharide, is used by many plants for structural stability. technology, engineering or math (STEM) educational standards. Describe how polymers are synthesized by combining two types of monomers with heat for a sufficient period of time. In the associated activity, Let's Make Silly Putty, studentsuse hydroxy tetraborate to form four covalent bonds between two poly(vinyl alcohol) chains when making imitation Silly Putty. A cross-link is a covalent bond formed between two polymer chains in a material (see Figure 5). A sustainable polymer is a plastic material that addresses the needs of consumers without damaging our environment, health, and economy. Polymeric materials are usually derived from petroleum or oil, but significant research is underway to develop novel methods of producing these materials using renewable energy sources. A polymer can be an end product in itself, or it can be an ingredient that changes the properties of another product. natural polymer: A polymer that is synthesized naturally by a plant or organism. This slide is very important to help students start thinking about the upcoming design challenge (in the associated activity). Here we will list some of the important uses of polymers in our everyday life. Lesson, High School Polymeric materials are usually derived from petroleum or oil, but significant research is underway to develop novel methods of … A polymer network consists of many polymer chains connected through a number of covalent linkages called cross-links. Additionally, have students each locate a material made from a polymer and be prepared to explain its chemical structure to the class.

This type of polymer is used in the manufacture of fabrics such as cotton, silk, wool, nylon, etc. Use this opportunity to identify the seven recycling codes (see Figure 6) and discuss the chemical properties of each plastic material. Students make two different formulations of imitation Silly Putty with varying degrees of cross-linking. some examples of such uses are listed below. Polyurethanes are used in foams, paints, adhesives and spandex. Its post-recycled material has found a niche application as a polyester insulation fiber used in winter jackets, pillows, bedding and carpeting. monomer: The building block of polymers. Can you guess what does? In order to influence the material properties of the silly putty students make, they will need to determine the amount of tetrahydroxyborate anion or cross-linking agent that is incorporated into the polymer. The origin of man-made polymers traces back to Central America and the ancient Aztecs, Olmecs and Mayas, who all made a form of rubber by combining natural latex found in plants with the juice of morning glory vines [source: Kaufman ]. This information gives students an idea for how to approach the design challenge after they make two different formulations of a poly(vinyl alcohol) silly putty. Therefore in engineering applications polymers are heavily used to replace costly materials whenever possible. Plastics, polythene, and rubber are well known polymers that are found a… Most of the polymers we talk about here are linear polymers. When no cross-links are present to chemically link the chain together, the chains are able to move much more freely. Although recycling codes are usually placed on polymeric materials, not all polymeric materials used in consumer products are labeled with recycling coded and not all polymeric materials are actually recycled. These covalent bonds cause the polymer chains within a polymeric material to become networked. One of the first uses of this material was in the Manhattan Project as a coating of valves and as a sealant in tubes containing uranium hexafluoride (highly radioactive material). Note: The animation in the attached PowerPoint presentation (v.11.5.5 or higher) requires Quicktime (v. 7.7 or higher). This special issue of Biomacromolecules highlights research from The International Polymer Colloid Group (IPCG), which was founded in 1972 as a forum for the exchange of ideas and emerging research activities for scientists and engineers from both academia and industry who study or use polymer colloids. Remember, cross-linking affects polymeric material properties by limiting the motion of individual polymer chains within a material (as highlighted visually in Figure 5). In this activity, polymers are used as illustrative materials for intermolecular bonds to help students to learn how the structures of polymers relate to their practical uses and properties. Polymers are used to make electronic components, paint, plastic bottles, sunglass lenses, DVDs and so much more! Polymers are encountered in everyday life and are used for many purposes! Polymers. Ask them to bring in examples not mentioned in the lesson presentation and talk about their polymer types and properties. Aromatic rings (also known as aromatic compounds or arenes) are hydrocarbons that contain benzene. Polymers are widely used advanced materials, which are found almost in every material used in our daily life. Benzene, C6H6, is often drawn as a ring of six carbon atoms, with alternating double bonds and single bonds as shown below. Art Director: Juan José Sepúlveda Ramírez. 1. In the form of fibers and non … Natural polymers were used for their chemical properties long before they were understood in the chemistry laboratory: Wool, leather, and flax were processed into fibers to make clothing; animal bone was boiled down to … These long chains confer interesting physical properties, such as strength and hardness, qualities that short molecules simply cannot provide. Thus, the degree of cross-linking throughout a material is very important in understanding how the physical properties of the material change. In industrial field : PLA can also be used as a decomposable packaging material, either cast, injection-molded, or spun. This means that non-covalent interactions between pi-bond electrons available in one polymer chain can interact with aromatic rings on another polymer chain when they are in close proximity. Many of the same units (or mers) are connected together to form a long chain or polymer. Figure 1: Common applications for polymeric materials.copyrightCopyright © 2011 Cherelle Bishop, Colorado State University, Figures 1 and 2 list just a few examples of the many ways that polymeric materials have changed our day-to-day lives through primarily low-cost, mass-produced materials. Research Projects: Have students (either in small groups or individually) research an assigned polymeric material, investigating its chemical properties, processing techniques and applications. This fact alone makes recycling all of these different plastic materials challenging, time consuming and costly. For example, the demand for lightweight parts and vehicles using recycled materials challenges engineers to make "smart polymers" that change their properties according to their environments. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. The "no cross-link" material has free-flowing polymer chains and stretches if force is applied to either end of the material chains. Polymers are everywhere! Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. (Hold up a pair of sunglasses, a plastic bag, and a CD case for the class to see. PVC safely delivers flammable oxygen in … Using Figure 2, write on the classroom board the chemical name and structure for each material. PARACHUTES. 1. CREDIT CARDS.

New York, NY: Oxford University Press, 1995, pp. The plastic or rubber items you encounter daily are all a type of polymer [source: Larsen]. Most of these types of materials are easy to produce and have a low cost. a project of D2L (www.achievementstandards.org). Ester functional groups are a less polar functional group than an alcohol group. BOTTLES. Polymers are chains made of monomer subunits. HS-PS2-6. In general, cross-links tend to make the polymer chain closer together and cause the material to become more rigid. Used for manufacturing optical fiber cables, drumheads, automotive industry, ropes, wire ropes and cables. Polyurethanes are connected by urethane linkages. (Another example would be to link student hands, paper clips, or strips of paper to form a chain). 12). It is used in the manufacture of tyre ,cords, fabrics, and ropes. For example, the polymer polyethylene has an ethylene backbone (CH2CH2). The following are the most useful polymers in our daily life - The polymer called Polyethylene is used in plastic bags and film wraps. The inclusion of a chlorine atom introduces a change in the physical properties of the overall material. Polymers Found in Nature. Figure 5: Cross-linking within a polymer.copyrightCopyright © 2011 Cherelle Bishop, Colorado State University. (Listen to student responses.) When many long polymer chains with a large number of cross-links are present within a material, the chains are chemically linked, making the material more rigid. This Uses of Polymers Video is suitable for 10th - Higher Ed. within type by subtype, then by grade, etc. Polyacrylamides are used in a various applications ranging from water purifiers, paper coating, cosmetic additives, photographic emulsion and contact lenses. These blended and composite plastics may not be able to use the same recycling process, making recycling costly and challenging for them. Examine how plastics are used and polymers synthesized. Most curricular materials in TeachEngineering are hierarchically organized; Those single bonds between atoms in the backbone can swivel around a bit, like paper clips hooked together end-to-end.
