摘　　要：以水为溶剂,分别选用对甲苯磺酸钠、高氯酸锂、硫酸钠为支持电解质,用电化学法合成聚3,4-乙撑二氧噻吩(PEDOT)膜。采用线性扫描伏安法(LSV)确定了合适的聚合电位;采用循环伏安法(CV)、电化学交流阻抗谱(EIS)研究了PEDOT膜的电化学行为。结果表明,掺杂阴离子种类对膜的循环伏安特性、EIS曲线等有很大的影响;此外研究了掺杂不同阴离子的PEDOT膜对电极的粘接性能,发现粘接性能也与阴离子种类有关。Conducting polymer poly （3, 4-ethylenedioxythiophene） （PEDOT） film electrodes were prepared hy electrochemical polymerization from aqueous solution containing 0. 01 mol/L 3, 4-ethylenedioxythiophene （EDOT）, with 0. 1 mol/L supporting electrolyte： TsONa, LiClO4, and Na2SO4, respectively. The optimal value of the applied potential was determined by using Linear Sweep Vohammetry （LSV）. Electrochemical behavior of PEDOT film electrodes was investigated by cyclic vohammetry （CV） and electrochemical impedance spectroscopy （EIS）. It shows that different dopants have a great influence on CV and EIS curves. In addition, the adhesion of PEDOT films on electrode was studied. It is found that different that dopants also have a great effect on adhesion of PEDOT films.
