摘　　要：以水为溶剂、对甲苯磺酸钠为支持电解质，在不锈钢电极上用电化学法合成了聚吡咯膜（ＰＰＹ膜），发现苯磺酸的存在能更有效地提高ＰＰＹ膜的电导率。在改进的电化学合成条件下，制得了电导率达１５Ｓ／ｃｍ，拉断强度为２５ＭＰａ，拉断伸长率达８％，并能作１８０°弯折的ＰＰＹ膜，产品的电导率有所提高，机械性能明显改善。This paper deals with electrochemical synthetic polypyrrole(PPY) fims prepared by utilizing supporting electrolyte of sodium p_ toluenesulfonate in aqueous solution on stainless steel electrodes.It is found that the existence of benzenesulfonic acid somewhat contribute to increasing conductivity and improving mechanical properties of PPY film with its electrical conductivity 15 S/cm,tensile strength 25 MPa,elongation 8% and with its 180° bending possible.
