In order to improve the flexibility and the anti‐static properties of poly‐( p ‐phenylene‐terephthalamide) (PPTA), the copolymer of p ‐phenylene diamine, p,p ′‐diaminodiphenyl ether and terephthaloyl chloride (PPDTA) was synthesized. This copolyamide PPDTA was mixed with electrically conductive polyaniline (PAn) in concentrated sulphuric acid solution, and was processed to form film, or fibre, of the new composite PAn/PPDTA with high strength and good electrical conductivity. The composite is a lyotropic liquid crystalline polymer with electrical conductivity 10 −1 S/cm. The surface morphology of the PAn/PPDTA composite consists of an oriented fibre‐like texture.
