POLY(N-VINYLCARBAZOLE) AND POLYPYRROLE COMPOSITES SYNTHESIZED BY LASER-ELECTROCHEMICAL POLYMERIZATION

A black and flexible film of poly(N-vinylcarbazole)-polypyrrole (PVK-P PY) composite with conductivity of 10 S/cm at room temperature was syn thesized by laser-electrochemical polymerization. The conductivity of PVK-PPY composites synthesized by laser-electrochemical polymerization was enhanced by one order magnitude compared with electrochemical pol ymerization due to photoelectrochemical or photochemical reaction and a thermal effect introduced by laser irradiation during electrochemica l polymerization. Effects of the ratio of PVK to pyrrole monomer, lase r energy density and wavelength on the structure and conductivity of t he resulting composites are discussed.
