Poly(styrene-b-2-vinylpyridine) diblock copolymer films with horizontally oriented lamellar microdomains were obtained by the casting method. Poly(2-vinylpyridine) (P2VP) layers were not only quaternized but also crosslinked with 1,4-diiodobutane vapour with the intention of immobilizing the supermolecular structure. Cu 2 ? ions (oxidant) were introduced into P2VP layers by complexation based on the pyridine nitrogen interacting with the metal ions. Electrically conducting films were synthesized with such an oxidizing agent being added to a mixture of pyrrole and water vapour. The element distributions on a vertical section of the composite films were measured by energy dispersive X-ray spectrometry. These films showed conductivities of 10-1 S cm- 1 parallel to the film plane and had high anisotropic conductivity.
