用循环伏安法研究了吡咯在不同金属基底不同支持电解质中的聚合过程，对不同基底上制备的聚吡咯膜进行了电化学、扫描电镜、表面能谱等方面的研究，考察了聚吡咯膜电极对ＮＯ_３－离子的电位响应情况，结果表明，不同基底不同支持电解质在不同的吡咯浓度中表现出各异的伏安行为，经电化学处理的聚吡咯膜电极均对ＮＯ_３－呈Ｎｅｒｎｓｔ响应，扫描电镜观察表明除Ｐｔ基底外在其它基底上制备的聚吡咯膜均呈颗粒性球状堆集。
Cyclic voltammetry was used to study the polymerization process of pyrrole in different support electrolytes with different metal substrates. Electrochemical, scanning electron microscopy and surface energy spectra of polypyrrole films prepared on different substrates were investigated. The results showed that the different supporting electrolytes of different substrates exhibited different voltammetric behavior at different pyrrole concentrations. The electrodeposited polypyrrole film electrodes all showed Nernst response to NO_3-, Scanning electron microscopy showed that the polypyrrole films prepared on other substrates except Pt substrate were all aggregated into spherical particles.
