中文摘要：

采用双功能性1，2-二（甲氧基二乙氧基硅基）乙烷为原料，在奥氏体304不锈钢表面制备了有机-无机杂化硅氧烷膜（BMBSE），并通过FTRA—IR、SEM、EIS、动电位极化曲线及接触角测量仪对薄膜的性能进行测试和表征。结果表明，致密完整无缺陷的双功能性BMBSE硅氧烷通过形成Si-O-Fe化学键与不锈钢基体结合；硅烷膜与水的接触角为94．2°，具有一定的疏水性；在55％的溴化锂溶液中的动电位极化曲线和EIS测试表明，双功能性硅氧烷BMBSE膜极大的改善了不锈钢的耐腐蚀能力。同时，给出了不锈钢表面双功能性硅氧烷BMBSE膜的阻抗模型以及相关拟合参数。

英文摘要：

Functional bis-silanes Bis-1, 2-[methylbisethoxysilyl] ethane （BMBSE） film was prepared on SUS 304 stainless steel. The structures and properties of the film was investigated by FTAR-IR, Scanning electron microscopy （SEM）, Electrochemical impedance spectroscopy （EIS）, Potentiodynamically polarization. The resuits showed that a BMBSE films were successfully deposited on SUS 304 stainless steel. The contact angle of the films was 94.2° and the hydrophobic film was presented. The results of Potentiodynamically polarization and EIS in 55 wt% LiBr solutions indicated that the film obviously improved the anti-corrosion performance of SUS 304 stainless steel. The impedance models and EIS simulation data of BMBSE films covered stainless steel in LiBr solution were also proposed in the present work.
