| 摘 要： | 以寻求低成本,高收益的探索思路为基础,制备出一种新式自组装分子膜,将其组装到金属体表面,进而达到防止金属腐蚀的目的。以水杨醛与乙二胺为原料,合成出乙二胺缩水杨醛Schiff碱,确定了最佳合成条件。对产物进行了熔点测定,红外光谱（IR）分析及质谱（MS）分析,确定制备的产物即为乙二胺缩水杨Schiff碱,并首次将其配制于花生油溶液中。将Schiff碱自组装到银片表面,利用金相显微镜观察Schiff碱的成膜现象;用循环伏安技术对自组装膜进行分析。实验结果表明,Schiff碱自组装分子膜能有效抑制异相电子的转移,组装速度快且性能稳定,减少了银片机体的腐蚀。总结了Schiff碱自组装分子膜对金属防护的效用和价值。
