| 摘 要： | 自组装膜对金属防腐蚀有极好的效用。为了进一步弄清聚乙烯吡咯烷酮对铜的缓蚀性能,用自组装技术在铜电极表面制备了聚乙烯吡咯烷酮自组装膜,利用电化学方法研究了自组装膜对铜在NaCl溶液中的缓蚀作用。结果表明,在0.5mol/LNaCl溶液中,随组装时间的增加,铜电极的电荷传递电阻增大,腐蚀电流密度下降,组装24h后对铜的缓蚀效率为99.9%,缓蚀性能优异。

| Abstract: | Polyvinylpyrrolidone (PVP) film was pre-pared on the surface of copper electrode by using self-assembly technique.The inhibitive action of the self-assembled film for Cu substrate in the aqueous solution of NaCl was investigated by using electrochemical methods.It was found that the self-assembled PVP film was able to increase the charge transfer resistance and de-crease the corrosion current density of the Cu electrode in the solu-tion of 0.5 mol/L NaCl.The self-assembled PVP film obtained af-ter24-hour se... |
