电解质溶液对聚吡咯电聚合中过氧化行为的影响
Effects of Electrolyte Solutions on Overoxidation of Polypyrrole During Its Electrochemical Polymerization
摘要
Abstract
Polypyrrole(Ppy) was prepared by cyclic voltammetry on a platinum electrode in H2SO4/H2O and yClO4/CH3CN solutions, respectively. The effects of electrolyte solutions on overoxidation of polypyirole during its electrochemical polymerization were studied by in situ spectroelectrochemical measurements. Compared with the solution of H2SO4/H2O, the overoxidative peak potential of polypyrrole in LiClO4/CH3CN was positively shifted by 0. 42 V. The results show that theβ-C of the pentacycle is oxidized to oxygen-containing groups such as C-OH and C =O during the overoxidation of polypyrrole at high potentials. Polypyrrole partially degraded with the formation of CO2 in H2SO4/H2O solutions, which resulted in loss of conductivity, and did not obviously degrade during overoxidation in the solution UC1O4/CH3CN at the higher potentials.关键词
