摘要
在不同比例 L-半胱胺酸 /二硫醇混合溶液中制备了混合自组装膜修饰电极。经过 L-半胱胺酸的还原脱附后 ,利用循环伏安技术研究了吡咯在 L -半胱胺酸 /二硫醇自组装膜修饰电极表面聚合的过程和影响聚合的几个因素。实验结果表明 ,下面的几个因素影响着吡咯在自组装膜上的聚合 :L-半胱胺酸在混合膜中的比例、支持电解质 p H的大小以及聚合单体分子的大小。
Patterned self assembled mixed monolayers have been fabricated by immersing the electrode into the mixed solution of L cysteine and C 2S 2H 6 with different ratio. The electrochemical deposition of polypyrrole has been investigated at the patterned mixed monolayers by cyclic voltammetry after the reductive desorption of L cysteine in alkaline. The results show that the following factors affect the polymer growth. They are the pH value of the supporting solution,the ratio of the reductive desorption L cysteine and the volume of the polymerizative molecule.
