【Abstract】 Polyaniline was prepared by chemical method and the effect of oxidizing agent, doping agent, reacting temperature and time on the electrical conductivity and the rate of productivity of PAn was investigated. Under the chosed working condition, the electrical conductivity of the polyaniline prepared is 5.6 S/cm and the rate of productivity of this PAn is 94%. A kind of complex polymerical electrode material was prepared by mixing PAn with electric powder, whose capability of charge and discharge was tested under fixed electrical current. The result indicates: the voltage of charge and discharge is high, and when the discharge current is 4 mA/cm 2 and terminative voltage is 1.2 V, the discharge time can last 16.5 h and discharge capacity is large.更多还原
