| 摘 要： | 在中性溶液中用重复电位扫描法在玻碳电极上制备了中性红聚合膜.中性红的聚合是在高电位引发下,氧化中性红产生自由基发生链式引发聚合.用铁氰化钾作为探针采用循环伏安法和电化学扫描电镜表征了不同聚合圈数的电极的表面性质.随着扫描圈数的增加,聚合膜的厚度也增加,同时电极由导体向绝缘体转变.电极表面的形貌图也说明了这一现象.

| Abstract: | The formation of a radical cation, by electrochemical oxidation of the neutral red dye in neutral aqueous solution, is controlled by diffusion towards the glassy carbon electrode surface. The polymer film was studied by cyclic voltammetry and SECM. The modified electrode change from conductor to nonconductor with number of circle increased. And SECM graph shows the same phenomenon. |
