Polyaniline (PAn) was synthesized by chemical oxidation polymerization. The conductive polymer doped by camphor sulfonic acid (CSA) and a matrix polymer, polyamide66, polyamide1010 or polyamide11, were dissolved in m-cresol and the blend solution was cast in a glass and dried for preparing polyaniline composite films. Conductivity was from 10 -6 to 10 0 Ω -1 ·cm -1 with different weight fraction of PAn-CSA. The crystallization of the films was studied by means of differential scanning calorimeter (DSC). The treatment of the composite films in different pH value solution would result in decrease of conductivity, especially in an alkaline solution.
