摘　　要：以可溶性酚醛树脂为碳前驱体,三嵌段共聚物F127为模板剂,碳球为填充相,经旋涂及溶剂蒸发诱导自组装,在不锈钢基体上构筑了具有高疏水性的碳球/有序介孔碳微纳米复合涂层。进一步利用PT-FE进行表面氟化修饰,获得了超疏水性能,润湿角达142°。扫描电子显微镜显示该复合涂层具有微米级褶皱/纳米级介孔孔道的复合结构。在模拟的海洋环境下,经过复合涂层改性的金属基体腐蚀电位正移了0.73V,腐蚀电流下降了4个数量级,防腐蚀效率高达99.9%以上,说明该涂层具有十分优良的防腐蚀性能。Micro-nano carbon spheres/ordered mesoporous carbon composite coatings were prepared on the stainless steel substrate through the spinning technique and evaporation induced self-assembly using soluble phenolic resins as carbon precursor,F127 as template-directing agent and carbon spheres as filler.The high rhydrophobic surface was obtained by the fluoridation modification and the contact angle could be arrived at 142°.Scanning electron microscope（SEM） indicated that the prepared composite coatings possessed the novel structure consisted of micro drape full of visible mesopores.Under the simulated marine environment,the corrosion potential of modified composite coatings was increased by 0.73V,and the corrosion current was decreased by 3-4 orders of magnitude.The anti-corrosion efficiency was calculated as high as 99.9 %,indicating the excellent protective performance.
