    uses of polymers in daily activities

    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. This work was developed by the Colorado Higher-Education Interdisciplinary Project (CHIP) in the Department of Electrical and Computer Engineering, based upon collaborative work supported by National Science Foundation grant no. At the end of the animation, a final polymer strand is show in an A-B-A-B pattern. technology, engineering or math (STEM) educational standards. Acids are common chemicals and can be found everywhere even in our food. 0841259. In the form of a film, it shrinks upon heating, allowing it to be used in shrink tunnels. The Great Pacific Garbage Patch (GPGP) is an intriguing and publicized environmental problem. Dear User, please complete the form below in order to recommend the Artdaily newsletter to someone you know. The video includes a discussion of the hazards of disposing of non-recycled plastics, as well as the search for biodegradable polymer options. natural polymer: A polymer that is synthesized naturally by a plant or organism. Attraction and repulsion between electric charges at the atomic scale explain the structure, properties, and transformations of matter, as well as the contact forces between material objects. Polyethylene is one of the most common polymeric materials found in plastic packaging, bottles and shopping bags. 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). 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. Ester functional groups are a less polar functional group than an alcohol group. Used for manufacturing optical fiber cables, drumheads, automotive industry, ropes, wire ropes and cables. The strengths of a polyethylene plastic bag and a water pipe made from cross-linked polyethylene are very different. PARACHUTES. Polymers are used very widely in the production, distribution, packaging and preparation of food. Monomers can be combined in various repeating patterns to form different types of polymers. Again, polyacrylamide can be derived from polyethylene by substituting a hydrogen atom with an amide functional group. Polymers can be made into clear, waterproof films. (Answer: The transparent portion of the Nalgene is polycarbonate, but the lids are not made from polycarbonate. Bottles, toys, containers, trays, disposable glasses and plates, tv cabinets and lids are some of the daily-used products made up of polystyrene. 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. Use this as an opportunity to incorporate scientific writing guides, electronic researching tools, and scientific citation into the class. London, UK: Royal Society of Chemistry, 2006. Introduce your organic chemistry class to common materials formed from polymers, such as nylon, kevlar, and styrofoam. Polymers are formed from hydrocarbons, hydrocarbon derivatives, or sometimes from silicon. Research Projects: Have students (either in small groups or individually) research an assigned polymeric material, investigating its chemical properties, processing techniques and applications. Polymers are used to make electronic components, paint, plastic bottles, sunglass lenses, DVDs and so much more! Polymers are widely used advanced materials, which are found almost in every material used in our daily life. In the ASN, standards are hierarchically structured: first by source; e.g., by state; within source by type; e.g., science or mathematics; Polymers are very large molecules compared to water. The next monomer unit, featured in Figure 2, is polycarbonate. Polymers become the raw materials for products we now use every day, including: synthetic clothing, fiberglass, plastic bags, nylon bearing, polyethylene cups, epoxy glue, silicone heart valves, Teflon-coated cookware and our personal favorite, polymer based paints. Applications of polymer in daily life. Plastics, polythene, and rubber are well known polymers that are found a… i.e., most hands-on activities are part of lessons, lessons are grouped into multiday Polymers are a type of material extensively used in both domestic and industrial applications. Do you agree with this alignment? Therefore in engineering applications polymers are heavily used to replace costly materials whenever possible. 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. Through exploring this complex issue, students gain insight into aspects of chemistry, oceanography, fluids, environmental science, life science and even international policy. 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 ]. Teflon: Polytetrafluoroethylene (PTFE) is a polymer similar to polyethylene, where hydrogen atoms are substituted by fluorine. An illustration of the chemical link between two polymer chains. But are oil-based polymers sustainable? Homework: Lead a class discussion about possible types of plastics that students use at home. (Another example would be to link student hands, paper clips, or strips of paper to form a chain). The plastic or rubber items you encounter daily are all a type of polymer [source: Larsen]. Museums, Exhibits, Artists, Milestones, Digital Art, Architecture, Photography, Photographers, Special Photos, Special Reports, Featured Stories, Auctions, Art … (Hold up a pair of sunglasses, a plastic bag, and a CD case for the class to see. 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. 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 … Communicate scientific and technical information about why the molecular-level structure is important in the functioning of designed materials. 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. What are some items made from polymeric materials that you frequently use? COOKWARES. Polymers are encountered in everyday life and are used for many purposes! 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. Thanks for your feedback! copolymer: A polymer made from two or more types of monomer subunits. A monomer is a basic building block of a polymer. 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. Describe examples how polymers are used in everyday life. For example, needles used for vaccines and IVs use a plastic casing typically made of polyurethane. 1. Lesson, Copyright © 2012 Cherelle Bishop, Colorado State University. Any opinions, findings, conclusions or recommendations expressed in this material are those of the author(s) and do not necessarily reflect the views of the National Science Foundation. about the process of development and the design and performance of a proposed process or system) in multiple formats (including orally, graphically, textually, and mathematically). Let us check it out some uses of polymers. 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. Polymers are both found in nature and manufactured in laboratories. A familiarity with basic chemistry concepts. The following are the most useful polymers in our daily life - The polymer called Polyethylene is used in plastic bags and film wraps. 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. 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. Frequently, this is because some polymeric materials are extremely durable, making recycling of the material costly and time consuming. Consumer products also typically use an initial stamp to signify the chemical compositions of the polymer used to create the material. (Present the following information to students as you show them the eight-slide Polymer Presentation, a PowerPoint file. (Listen to student responses.) Polyethylene is utilized in the bottles, electrical insulation, toys, etc; Polyvinyl Chloride( PVC) is used in siding, pipes,flooring purposes. Bahadur, P. and Sastry, N. V.
