Properties of Conductive Polymeric Composites and its Applications, Volume -I

Introduction to polymers: Polymers are substances whose molecules have high molar masses and are composed of a large number of repeating units. There are both naturally occurring and synthetic polymers. Among naturally occurring polymers are proteins, starches, cellulose, and latex. Synthetic polymers are produced commercially on a very large scale and have a wide range of properties and uses. The materials commonly called plastics are all synthetic polymers. Most of the organic substances found in living matter, such as protein, wood, chitin, resins etc. are polymers. Many synthetic materials, such as plastics, fibers, adhesives, are also to large extent polymeric substances.
