不锈钢表面Schiff碱自组装分子膜的制备及性能
Synthesis and Properties of Schiff Base Self-Assembled Monolayers on Stainless Steel Surface
摘要
Abstract
A new Schiff base was synthesized from ethylenediamine and acetylacetone using hydrochloric acid as catalyst. The yield of the target base was about 73. 2 %. 1H NMR and FT-IR were performed to determine the structure of the final product. Polarization curves, electrochemical impedance and the corrosion potential-time curves of the Schiff base self-assembled membranes on stainless steel ( SS/SAMs) were analyzed. The result showed that, in 1.0 mol/L HC1, the SS/SAMs can effectively inhibit the heterogeneous electron transfer, promote the stainless steel surface passivation, and reduce corrosion of the stainless steel substrate. Effectiveness and value of metal protection of Schiff base were summarized.关键词
