Preparation and characterization of processable electroactive polyaniline–polyvinyl alcohol composite

In this paper, the preparation and characterization of polyaniline–polyvinyl alcohol composites is described. The polyaniline composite was synthesized by chemical polymerization of aniline in media containing polyvinyl alcohol (10%, w/w). Oxidation of aniline results in a stable water based polyaniline dispersion, which can be cast to form a mechanically robust film. ectrical conductivity of the films increased with increasing amount of polyaniline to a high value of 2.5 S cm−1. Cyclic voltammograms revealed that the composite materials are electroactive.
