The preparation of the electrodes for electrochemical studies was as follows: Cu–In–S annealed thin film samples were covered with a silver epoxy solution and heated to 40 ◦C for 4 h. The electric contacts of the samples were done by a copper wire, which was attached to the film with conductive silver paint. The body of the wire was encased in glass tubing and insulated using an epoxy coating that also covered thesample edges. The total area expose of the electrode was 0.5 cm. 请问要环氧银为什么要覆盖在膜上，研究膜的性质，如果覆盖上东西，循环伏安做的不就是所覆盖东西的性质了么？需要 需要说明，Cu–In–S是沉积在了导电玻璃上的
