ELECTRICALLY CONDUCTIVE COMPOSITE OF POLYPYRROLE AND LIQUID-CRYSTALLINE COPOLY(ESTER-AMIDE)S

The modification of the mechanical properties of polypyrrole (PPY) by electrochemical preparation of conductive composite film from pyrrole (PY) and three kinds of liquid crystalline copoly (ester-amide)-PEA (H), PEA (C), PEA (O)-are presented. The electrical conductivity of the PEA (H)/PPY, PEA (C)/PPY, and PEA (O)/PPY composites are the same order of magnitude as PPY. The mechanical properties of the composite films are much better than that of pure PPY, and the composite films have good conductivity and thermostability. (C) 1994 John Wiley & Sons, Inc.
