将亚甲基蓝（MB）分子引入到玻碳表面的Nafion聚合物膜中，制备了MB化学修饰电极。详细讨论了MB修饰聚合物膜电极的电化学行为。MB结合到聚合物膜的电极反应显示出可逆的，两个电子转移过程，具有良好的稳定性和重现性。半波电位E1/2 vs.从理论上推导了pH值，并通过实验验证了pH值对MB修饰聚合物膜电极的影响。讨论了支持电解质对电极的影响。
A methylene blue (MB) chemically modified electrode has been prepared by incorporating MB molecules into a Nafion polymer film on a glassy carbon surface. The electrochemical behaviour of the MB-modified polymer film electrode is discussed in detail. The electrode reaction of MB bound to the polymer film shows a reversible, two-electron transfer process with good stability and reproducibility. The equation of half-wave potential E1/2vs. pH was deduced theoretically and was proved to be reasonable experimentally by the effect of solution pH on the MB-modified polymer-film electrode. The influence of supporting electrolytes on the electrode is discussed.
