Abstract
Abstract Polymeric materials consisting essentially of a polymer of recurring units of a five-membered oxygen family heterocyclic ring which is selected from furan, thiophene, selenophene, tellurophene and derivatives thereof. The polymer is doped with anions of the specific type. A method for producing the polymeric materials is also described which comprises electrochemically polymerizing a five-membered oxygen family heterocyclic compound in coexistence with an acceptor with or without use of a supporting electrolyte in such a way that anions of the specific type is taken in the polymerized heterocyclic compound. The polymeric material is obtained in the form of a dense tenacious film.
