| 摘 要： | 通过电化学途径和化学途径在ＹＢａ＿２Ｃｕ＿３Ｏ＿７超导体表面制备了导电高分子聚吡咯膜，用以保护超导体不受环境作用的影响，实验结果发现电化学过程能破坏ＹＢａ＿２Ｃｕ＿Ｏ＿７的超导性，而采用化学法制备的聚吡咯和聚氯乙烯混和材料包覆在ＹＢａ＿２Ｃｕ＿３Ｏ＿７表面后，超导体不仅保持原有超导性，而且有很好的保护超导体免遭环境中酸和水作用的能力。

| Abstract: | Conductive polypyrrole(PPy ) films were prepared on the surface of YBa2Cu3O7superconductors through electrochemical synthesis or chemical method to prevent YBa2CusO7from corroding in reactive environments.The resuIts showed that the electrochemical poly-merization destroyed the superconductivity of YBa2Cu3O7,whereas the chemical coating ofPPy/PVC on YBa2h3O7 did not affect the superconductivity.Furthermore,the chemicalPPy/PVC coatings could greatly improve the superconductors stability in water and acid. |

| Keywords: | YBa2CuO7 superconductor protection polypyrrole polyvinylchloride |
