The polyaniline coating may change the corrosion potential of steel from 150 mV to positive direction,and changed the corrosion current density from 10 -7 A/cm2 to 10 -8 A/cm2.The antiseptic ability of steel has improved by coating with PAn.

• 聚苯胺涂层能使钢铁自然腐蚀电位正移 15 0 m V,钢铁腐蚀电流密度由 10 - 7A/ cm2变到 10 - 8A/ cm2 ,提高了钢铁的防腐蚀性能。
