Produção de blendas condutoras poliméricas de PANI/PVB

Abstract

The mixture of polymers, or polymer blends, is directly linked in into the production of new materials with properties many times superior to those found in pure form. Polyaniline is a polymer that has advantages over the others because it is easy to obtain, relatively low cost, stability under ambient conditions. Thus, the present work aimed at the synthesis of PANI / PVB polymer blends and characterization through conventional techniques such as infrared, visible ultraviolet spectroscopy and electrical characterization. The methodology used was based on the literature following the order of salt production, doping, no doping and blending production. The result was blends with conductive characteristics, presenting higher conduction of electric current in those with high concentrations (5 and 10%), but with low mechanical stability. Thus, it is concluded that the PANI / PVB blends are excellent candidates for various applications and studies related to them are of great contribution to scientific development.
