Ring stacking can also be observed between chains of polystyrene as with polycarbonate. The synthetic polymer Polystyrene is used in cabinets and in packaging. Examine how plastics are used and polymers synthesized. 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. They are the chemical substances; ranging in pH scale from 0 to 7. Boca Raton, FL: CRC Press, 2008. Benzene, C6H6, is often drawn as a ring of six carbon atoms, with alternating double bonds and single bonds as shown below. To illustrate this point, imagine a kink in a garden hose; the kinks loosen after enough force is applied, which is similar to how polymeric materials stretch. 9 - Polycarbonate monomer includes the integration of two, six-membered aromatic rings separated by a carbon atom that has two methyl groups attached. Polymers are encountered in everyday life and are used for many purposes! 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. This type of polymer is used in the manufacture of fabrics such as cotton, silk, wool, nylon, etc. All 100,000+ K-12 STEM standards covered in TeachEngineering are collected, maintained and packaged by the Achievement Standards Network (ASN), After this lesson, students should be able to: Each TeachEngineering lesson or activity is correlated to one or more K-12 science, MATERIAL AND FIGURE REFRENCES:- polymerization: The process of chemically linking monomers in various patterns to produce a polymeric material. 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 a part of our every day life and without them around, this world would be very, very different, if not impossible to live in. Materials engineers rely on some polymers for their rigid strength, others for their flexibility, and still others for their resistance to corrosion. Do you agree with this alignment? The "no cross-link" material has free-flowing polymer chains and stretches if force is applied to either end of the material chains. Let’s check its everyday uses. Recycling Drive: Ask students to each bring in several examples of polymeric materials for a class recycling drive. Many of the same units (or mers) are connected together to form a long chain or 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. 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. Used for manufacturing optical fiber cables, drumheads, automotive industry, ropes, wire ropes and cables. Applications of polymer in daily life. Polyurethanes are connected by urethane linkages. (Bottom of slide from left to right:) The first two images show vascular grafts made from polytetrafluroethylene, with the second vascular graft (middle ) featuring roughness on the surface to promote integration of the vascular graft to the patient. Hydrochloric Acid (HCl) Polypropene finds usage in a broad range of industries such as textiles, packaging, stationery, plastics, aircraft, construction, rope, toys, etc. Polymers are used to make electronic components, paint, plastic bottles, sunglass lenses, DVDs and so much more! 1. 0841259. However, most people do not even know what a polymer is, or just how widespread they are around us. To make the use of recycled materials more common in consumer products, it helps to increase the demand by purchasing recycled materials or products that use post-recycled plastic. 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. Petrochemicals are chemicals derived from crude oil or petroleum. Predict how a cross-linker will cause a change in the physical properties of a polymer system and how molecular arrangements influence these materials properties. An illustration of the chemical link between two polymer chains. Over-aggressive mixing of slime in the plastic bags can lead to rupture, resulting in a slimy mess. technology, engineering or math (STEM) educational standards. (Another example would be to link student hands, paper clips, or strips of paper to form a chain). Materials challenging, time consuming putty with varying degrees of cross-linking on materials.
