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.
We have studied the electrochemical behavior of chemically synthesized polyaniline powder by slow kinetic potential scan.In this paper, polyaniline powder synthesized by potentiostatic electrolysis was studied in this paper.Powder prepared by this method has high purity due to the absence of oxidants in the synthetic solution This article also reported the AC impedance measurements of the polyaniline powder electrode AC impedance method used in polyaniline film conductivity and chemical synthesis of polypyrrole resistance measurement using hydrochloric acid, borofluoric acid, hydrofluoric acid, aniline are Analytical purity Aniline pressure distillation purification; Sulfuric acid is ultrapure; Phosphoric acid is analytical grade; Perchloric acid is superior grade pure. The solution is prepared with two distilled water.
