HIGH-QUALITY POLY(P-PHENYLENE) FILM PREPARED BY ELECTROCHEMICAL POLYMERIZATION OF BENZENE AT A STAINLESS STEEL ELECTRODE

摘要

Poly(p-phenylene) (PPP) film has been electrochemically deposited onto a stainless steel electrode surface by direct oxidation of benzene in BF3-diethyl ether solution at an applied potential of 1.7 V (vs Ag/AgCl). The morphology, conductivity and the mechanical property of the film were studied. As-grown PPP film has a conductivity of 2.7 S cm(-1). It has a high modulus of 1.2 x 10(10) dyne cm(-2) and a large tensile strength of 550-650 kg cm(-2). Furthermore, this film was flexible and could be easily cut into any shapes, such as fibres, circles, squares and triangles. (C) 1997 Elsevier Science Ltd. [References: 19]
