摘要

应用化学还原方法于水溶液中制备银纳米粒子,在十二烷基硫醇的保护下,将银纳米粒子从水相转移到了甲苯相,处理好的铁电极浸泡在含有十二烷基硫醇保护的银纳米粒子/甲苯溶液中,制得十二烷基硫醇/银纳米粒子自组装混合膜。电化学方法如交流阻抗谱(EIS)、极化曲线等研究该自组装膜在0.5 mol dm-3 H2SO4溶液中的缓蚀作用,XPS测试的吸收峰,证明了该自组装膜十二烷基硫醇和银纳米粒子之存在。

Abstract

The Ag nanoparticles were prepared in aqueous solutions through a chemical reduction method and transferred from water phase to toluene phase with the protection of 1-dodecanethiol (DDT). The polished iron electrode was immersed in the DDT-protected metal nanoparticles toluene solutions to form DDT/Ag nanoparticles self-assembled mixed films. Electrochemical methods such as electrochemical impedance spectroscopy and polarization curve measurement were used to study the inhibition properties of the self-assembled films in the 0.5 mol?L-1 H2SO4 solution. The appearance of elements such as S and Ag from the XPS data identified the presences of DDT and Ag nanoparticles.
