Electrically Conductive Composite of Polyaniline and Poly(p-Phenylene-Terephthalamide)

ABSTRACTThe improvement of the processibility and mechanical properties of poly-aniline (PAn) by processing a concentrated sulfuric acid solution of the mixture of chemically prepared conductive PAn powders and poly(p-phenylene-terephthalamide) (PPTA) in different weight ratios are presented.The concentrated sulfuric acid solution of PAn and PPTA were processed to films and threads, they are liquid crystalline conductive polymer composites, the electrical conductivities of the composites are between 10−4 -10−1 s/cm.PAn enhanced the tensile strength of PPTA, but does not effect the elongation. The morphology of the PPTA/PAn composite surfaces are fiberlike texture.
