Synthesis of Polyaniline Nylon 66 Conducting Composites

Abstract

Composites of polyaniline conducting polymers (polyaromatic amines) with synthetic polymers such as polyamides (nylons) can be processed from formic acid solvent through cast method. Formic acid was found to be a good solvent for preparation of polyaniline/nylon composites (PAn/Ny) as free standing films or coating on the surface of different inert substrates. The preparation conditions of PAn/Ny composite were optimized with regard to the mechanical properties and electrical conductivity. Chemical polymerization of polyaniline polyamide (nylon) composites with the procedure described in this paper provides the best way in order to prepare PAn/Ny composite membranes with high conductivity, uniformity and homogeneity. The procedure described can also be considered the only way for preparing PAn/Ny composites as coated on the surface of inert and conducting substrates such as glass or paper in order to make them conductors or semiconductor materials.
