化学修饰电极是当前电化学领域中十分活跃的崭新研究方向.它的出现扩展了电化学的研究和应用范围,有广阔的发展前途,已在电子转移、光电转换、催化、立体选择性有机合成以及选择富集测定等方面显出其优越性.最近,在多种化学修饰电极类型中,令人特别感兴趣的是具有电活性的聚合物膜电极.制备聚合物膜电极的方法很多,用等离子体聚合法可得高度交联的超薄膜,且化学和热稳定性均好.由于聚乙烯二茂铁膜修饰电极在电催化、光电催化、稳定电位及研究电荷转移机理方面的意义而引起了重视.但有关用等离子体聚合法制备的报道则不多.本文研究用固体的乙烯二茂铁单体经等离子体聚合在玻炭基底上制备聚乙烯二茂铁膜电极.研究了各种因素对等离子体聚合的影响.用循环伏安法研究了膜电极的电化学行为.
Chemically modified electrode is a new and active research direction in the field of electrochemistry and its appearance has expanded the research and application range of electrochemistry and has a bright future. It has been widely used in electron transfer, photoelectric conversion, catalysis, stereoselective organic synthesis As well as selection enrichment assays, etc. Recently, among many types of chemically modified electrodes, of particular interest are electro-active polymer membrane electrodes. There are many ways to prepare polymer membrane electrodes using Highly crosslinked ultrathin films are obtained by plasma polymerization and have good chemical and thermal stability due to the significance of electrocatalytic, photoelectrocatalytic, stable potentials and the study of the charge-transfer mechanism of polyethylene-ferrocene modified electrodes However, there are not many reports about the preparation by plasma polymerization.In this paper, polyethylene ferrocene membrane electrode was prepared by plasma polymerization of solid ethylene-ferrocene monomer on glassy carbon substrate. Effect of Factors on Plasma Polymerization The electrochemical behavior of the membrane electrode was investigated by cyclic voltammetry.
