Polyurethane-based conducting composites with polyaniline, polythiophene or polypyrrole are in the class of modern macromolecular materials that combine the toughness and elasticity of a polyurethane matrix with conductivity of intrinsically conducting polymers. Since the methods of preparation strongly influence the structure and properties of resulting composite/blend, this work aims at a systematic description of polyurethane-based conducting composites. This review has been structured to present an overview on preparations, characterisation and applications of polyurethane-based conducting materials with polyaniline, polythiophene or polypyrrole.
