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。

Abstract: The self-assembled monolayers(SAMs) was synthesized in order to seek low-cost and high-yield exploration of ideas. It was assembled to the metal surface, thus achieving the purpose of preventing metal corrosion. Salicylaldehyde-ethylenediamine Schiff base was synthesized with salicylaldehyde and ethylenediamine. Optimum conditions were identified. The products were certificated by melting point, infrared spectra and mass spectra. The result was that salicylaldehyde-ethylenediamine Schiff base was identified. The Schiff base was first served as additives in a peanut oil and self-assembled on the surface of silver. The SAMs were described with Jinxiang microscope technique. Simultaneously it was briefly characterized with CV method. The results show that the heterogeneous electron transfer can be inhibited by Schiff base SAMs. The assembling rate of SAMs is fast and stable. Corrosion of the silver strip body is reduced. Effectiveness and value of metal protection are summarized on Schiff base SAMs.
