Abstract

INTRODUCTION - The discovering of organic conducting polymers with relative ease synthesis by chemical and electrochemical polymerization of monomers, with diverse and interesting optical, physical, electrical and mechanical properties, added to practical application in processes, devices preparation and novel uses, makes this area of practical and commercial interest. These materials include conjugated and redox organic conducting polymers, copolymers and olygomers association forming organic conducting compounds. This type of materials can be prepared with specific characteristics, flexible or rigid, amorphous or crystalline, with different shapes, geometry and many others. Conducting polymers offer a unique combination of properties that make them attractive alternatives for certain materials currently used in microelectronics. These polymers are made conductor (doped) by reacting the conjugated polymer with an oxidizing or a reducing agent, or a protonic acid. The conductivity of these materials can be tuned by chemical manipulation of the polymer backbone, by the nature of the dopant, by the degree of doping, and by blending with other polymers. Polymeric materials are lightweight, easily processed, flexible, have potential applications at all levels of microelectronics, in the area of lithography, metallization, as corrosion-protecting coatings for metals and surfaces, as electro static dispersive protector for packages and housings of electronic equipment and with possible use in interconnection technology and as novel organic materials in electronic devices. Conducting polymers are promising transducers for chemsensors and biosensors owing to their unique electrical, electrochemical and optical properties that can be used to convert chemical information or biointeractions into electrical or optical signals.
