    Abstract: Composite materials comprising a carrier material and a film, applied thereto, of homopolymers or copolymers of pyrrole, thiophene, furan or aniline or polymerisable derivatives of these monomers, this film having a thickness of from 0.1 to 10 mu m, obtainable by oxidative polymerisation by means of an aqueous solution of an oxidant, by a) first wetting the carrier material with this solution and b) bringing the carrier material into contact with a solution of the monomer(s) in an organic solvent which is virtually homogeneously immiscible with water or by carrying out operations a) and b) in the reverse sequence. These composite materials are used to produce electrical and electronic devices.
