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.展开更多

The result shows that this composite film has very high conductive properties, the maximum value of conductivity reaches 0.173 S/cm at the concentration 0.75 mol. The influences of HClO 4 on the conductivity of the composite film are investigated.In addition,the electrode reaction progress is discussed with the result that obtained from SEM and FTIR analyzing.展开更多
