Polyphenylenediamine(PPD) film was prepared with organo sulfur compond (2-aminothiophenol, 1,2-ethanedithiol and 2-aminoeithaneethiol) adding lithium salt to increase conductivity for the case fo lithium secondary system. The thermal stability and morphology of conductive polymer synthesized were detcted by using SEM, TGA, DSC analysis. The elecrical conductivity were measured by four-probe method at N₂ atmosphere dry box. The electrical conductivity was showed good valuable about 1.2x l0¹ S/cm at room temperature.
