    Abstract

    The influence of high-energy electron irradiation on the conduction behavior at high current density of polyaniline (PANI) films doped with HCl and camphor sulfonic acid (HCSA), respectively, is reported. It is found that there exists an ohmic region under certain current density for both non-irradiated and irradiated samples. No significant change of the conductivity and maximum current density are observed if the sample is irradiated at room temperature and low dosage. The conductivity and maximum current density decrease with dosage if the samples are irradiated at high temperature. However, after redoping with 1 M HCl, the conductivity of these films can be recovered, while the maximum current density remains at a lower level. The DSC thermograms show that the crosslinking density of PANI-HCl film increases due to the high-energy electron irradiation.
