中文摘要：

采用电化学刻蚀-表面修饰-全氟聚醚油注入三步法在模板材料纯Al表面制备了仿猪笼草超滑表面,研究了仿生超滑表面对典型腐蚀微生物-硫酸盐还原菌的附着及所致腐蚀的影响。结果表明,仿生超滑表面在静态和动态环境均可明显抑制硫酸盐还原菌的附着,这主要是由于仿生超滑表面作为一种＂类液体＂表面,无法为细菌的附着提供锚点。同时,全氟聚醚油可通过阻止腐蚀性介质向基体的渗入,抑制基底Al的腐蚀过程。该研究的开展可为海洋微生物腐蚀防护材料的开发提供理论依据和模型。

英文摘要：

Microbiologically influenced corrosion（MIC） is an important corrosion form in marine environment. The development of novel technology for MIC inhibitionis of great significance for the utilization of marine source. In this research, a three-step procedure, including electrochemical etching, surface modification, and infusion of lubricant, was utilized to fabricate slippery liquid-infused porous surface（SLIPS） over Al. The effect of SLIPS on the adherence of sulfate reducing bacteria（SRB） and the SRB induced corrosion was studied. It was found that the SLIPS can inhibit the SRB adherence for the liquid- like property of SLIPS, which hardly provides anchors for the SRB adherence. Furthermore, the lubricant layer existed over aluminum substrate can inhibit the penetration of corrosive medium, and thus provide an effective barrier between corrosive medium and Al- substrate. The as- fabricated SLIPS can maintain high stability in both static and dynamic seawater with SRB. This research will provide a sound reference for developing a novel method for MIC protection.
