Electrically Conductive Composite of Polypyrrole and Liquid Crystalline Aromatic Copolyamide

  • Jing-Sheng Bao (a1), C. C. Xu (a1), W. Cai (a2) and Xian-Tong Bi (a1)


The modification of the mechanical properties of polypyrrole(PPy) by electrochemical preparation of conductive composite film from pyrrole(Py) and two kinds of liquid crystalline copolyamide of poly(p-phenylene-terephthal- amide)(PPTA) poly(p-phenyleneterephthalamide/diphenyl ether terephthal- amide) (PPTA[0]) and poly(p-phenyleneterephthalamide/diphenyl methane tere-phthalamide) (PPTA[C]) are presented.

The electrical conductivity of the PPTA[0]/PPy and PPTA[C]/PPy composites are the same order of magnitude as PPy or PPTA/PPy. The mechanical properties of the composite films are better than that of pure PPy. and the composite films have good electroactivlty and thermalstability.
