The electrochemical copolymerization of pyrrole and furan in a novel binary solvent system

Electrochemical copolymerization of furan and pyrrole was performed potenti ostatically in a binary solvent system consisting of boron trifluoride ethy l ether and additional ethyl ether. The influence of applied polymerization potential and the monomer feed ratio of furan and pyrrole on the synthesis of copolymer was investigated. The higher potential favored the incorporat ion of furan units into the copolymer, while the amount of pyrrole units in corporated into the film increased with the increasing concentration of pyr role in the solution. The film obtained was characterized by cyclic voltamm etry, infrared and Raman spectroscopies. (C) 1999 Elsevier Science S.A. All rights reserved.
