用分子筛/高聚物悬浮液挥发法和分子筛/高聚物热熔法制备了两种分子筛/高聚物修饰电极,通过循环伏安法,考察了所制备电极修饰层的牢度和寿命,尤其是在反应条件下,修饰层的耐久性以及在修饰层中的分子物种的电响应的稳定性.结果显示,修饰层的牢度和寿命依赖于如下因素:修饰层中的高聚物种类、修饰层所使用的溶剂环境、修饰层中的分子筛粒子的大小、修饰层中分子筛与高聚物的比例、电解质溶液的温度以及电极与溶液间的相对运动
Two kinds of molecular sieve / polymer modified electrode were prepared by molecular sieve / polymer suspension volatilization and molecular sieve / polymer hot melt method. The cyclic voltammetry was used to investigate the fastness and life span of the modified electrode. Especially under reactive conditions, the durability of the modified layer and the stability of the electrical response of the molecular species in the modified layer. The results showed that the fastness and life span of the modified layer depend on the following factors: the type of polymer in the modified layer, the solvent environment used in the modified layer, the size of the molecular sieve particles in the modified layer, the molecular sieve and the polymer in the modified layer The ratio, the temperature of the electrolyte solution and the relative movement between the electrode and the solution
