STUDIES ON CONDUCTING POLYANILINES AND ITS COMPOSITES

Abstract

Plastic has many attributes, including light weight, corrosion resistance and design flexibility. An unlimited number of shapes and sizes of parts can easily be created with thousands of different grades of polymer. The plastic materials also appeal to engineers because it allows them to create single-piece components that simplify assembly. Traditionally, one of the only drawbacks of plastic has been its lack of electrical conductivity. Nearly 45 years ago, organic polymers were hard to believe conducting and almost all of its studies, publications and uses were based on its insulating properties. But, now it is being started to change. Nanotechnology is enabling the engineers to create hybrid materials that can be processed with traditional production methods, such as injection molding and laser welding. After the synthesis and developments of polyacetylene, a new field of conducting polymers has attracted the attention of many theoretical and experimental professionals working under various domains of science and technology through out the world. These new materials, also called synthetic metals, combine the electrical properties of metals with the advantages of polymers such as light weight, greater workability, resistance to corrosion and lower cost [1]. The major target of conductive polymer technology development has been to combine the electrical and optical properties of these new materials with the mechanical properties and processability of commodity bulk polymers. New products having properties difficult or impossible to achieve by existing materials like metals, ceramics etc, can now be produced by new conducting materials that offer significant application potential as substitute of these existing materials.
