    A polymer is a large molecule which is formed by repeated linkage of small molecule called monomers. Conducting polymer have been the subjects for many decades as possible synthetic metals. Many of these polymer, especially those with a conjugated pi-bond system ,often yield higher conductivity once having undergone the doping process. Polymers are typically insulators due to their very high resistivity .Insulators have tightly bound electrons so that nearly no electron flow occurs ,and they offer high resistance to charge flow. Conductance free electrons are needed. Conductivity in polymer can be induced by delocalizing their orbital with conjugated p-electron backbones. Discovered in the late seventies (1977) by Alan Heegar , Dr. Hideki…

    Organics polymers are emerging materials in various optical and optoelectronic applications due to their superior properties over conventional inorganic materials. For example, devices made out of organic polymers can be flexible, have better mechanical stability on impact, light weight and significantly effective in the cost of manufacturing. Due to these alluring properties, organic polymers are becoming extremely important in applications such as transparent/flexible optoelectronics,…

    The chemistry behind polymers, the substance from which plastic is made, is very important in the everyday lives of the average person. To start, “The simplest definition of a polymer is a useful chemical made of many repeating units” (“The Basics”). Further, polymers are not limited to just plastics, but all types of plastic are polymers (“Plastics”). Some examples of polymers include cellulose and DNA (“Plastics”). Plastics are used everywhere in life today, and understanding the way that they…

    Polymer - A word, which is connote for large molecules (that a molecule made from simple repeating units called monomers). The monomers are main building block of polymers. Polymers play an essential and ubiquitous role in everyday human life because of the extraordinary range of properties. Polymers are among the most widely used and important type of materials today. Polymers have been with us from the beginning of time; they form the very basis (building blocks) of life. Animals, plants all…

    Before we can talk about what a polymer is, we need to know about ATOMS and ELEMENTS and MOLECULES. To learn about atoms and elements and molecules, click here. Paul Lemur This is PAUL LEMUR. He's a lemur named Paul. Polymers are made up of many many molecules all strung together to form really long chains (and sometimes more complicated structures, too). What makes polymers so fun is that how they act depends on what kinds of molecules they're made up of and how they're put together. The…

    tract The inhibition efficiency of polymers are highly dependent on group functionalities as well as adsorption characteristics, electronic properties, and molecular weight. The modification of these properties pave the way for future research in inhibitor technology. Introduction The inherent protection of metals and their alloys used in industry are of the upmost importance when it comes to longevity and reliability of structures. Many chemical compounds have been developed over the years…

    to ever be created. They treated every creature with great respect. Though they took very little from the Earth, they were very grateful. To the right were the Polymers, a very mean-spirited group. This group found great pleasure in depleting Earth's bountiful lands, and destroying Earth's beautiful creatures. While the Aerosols were constantly trying to make peace and live in harmony, the Polymers craved constant chaos throughout the land. One…

    Kathy McCurry Kathy McCurry is a recent polymer convert. Her journey started a couple of years ago when a job loss left her with some free time as she gathered and researched other opportunities. As it happened, she had relocated for the job she lost, so she was alone in a strange town. She did, however, have a long-forgotten box of beads. In that box were some glass pendants she purchased while in China. Those pendants got her interested in making jewelry, which sent her onto a hunt on the…
