摘　　要：介绍了聚(3,4-乙撑二氧噻吩)(poly(3,4-ethylenedioxythiophene)简称为PEDT的导电机理,性质特点,应用前景及单体EDT的合成情况。通过聚苯乙烯磺酸(简称为PSS)掺杂,解决了聚(3,4-乙撑二氧噻吩)的加工问题,所得PEDT\PSS膜具有电导率高,很好的抗水解性和光稳定性及热稳定性(在110￣200度的高温下能耐1000h,其膜电导率几乎不变),已在固体电解电容器、抗静电涂层、电容器电极材料等方面获得成功应用。Conduetive mechanism, performances,and appliances of PEDT and synthesis of monomer EDT are presented. The problem with process was solved by doping with polystyrene sulfonie acid.The obtained PEDT/PSS film is characterized by its high conductivity （10s/cm）,high light transmissivity （almost transparent in the range of visible light ）.High meehnieal strength,high resistance to hydrolysis,high light stability and thermal stability （almost no change in resistance supposed to 110 to 200℃,1000h）.The film is successfully used in solid electrolytic capacitors.
