| 摘 要： | 我们曾用慢速动电位扫描法研究化学合成聚苯胺粉末的电化学行为.本文对恒电位电解合成聚苯胺粉末进行了研究.用这种方法制备的粉末由于合成溶液中不含氧化剂因而纯度高.本文还报导了这种聚苯胺粉末电极的交流阻抗测量结果.交流阻抗法曾用于聚苯胺膜的电导和化学合成聚吡咯的电阻测定. 所用盐酸、氟硼酸、硅氟酸、苯胺均为分析纯;苯胺经常压蒸馏提纯;硫酸为超纯;磷酸为分析纯;高氯酸为优级纯.溶液皆用两次蒸馏水配制.

| Abstract: | The redox electric charges of polyaniline synthesized by potentiostatic electrolysis in varius acids were mearsured,they were much higher than that of polyaniline synthesized by chemical method.The redox peaks of polyaniline synthesized at high anodic potential are decreased markedly.It might be caused by an irreversible degradation of polyaniline and/or a certain type of destruction of the polymer structure.A.C.impedance measurements at different potential show that the resistance of the polyaniline electrode varies with the electrode potential. |
