摘　　要：用电沉积方法在X90管线钢表面制备Cu保护层,经水热反应及全氟辛酸修饰后制备出CuO超疏水涂层。使用X射线衍射仪、扫描电子显微镜、红外光谱仪和接触角测量仪等手段对涂层表面的相组成、微观形貌、化学成分及润湿性进行表征,研究了涂层的机械稳定性、防粘附性和耐腐蚀性。结果表明,具有疏水性的全氟辛酸成功嫁接到了由"花瓣"状CuO组成的微纳米混合结构上,使涂层表面与水滴的接触角约为161.24°,滚动角为3°左右;这种涂层表面表现出良好的机械稳定性、防粘附性和耐腐蚀性。Superhydrophobic coating of CuO was prepared on X90 pipeline steel substrate by a three step process, i.e. first a Cu protective layer was electrodeposited on the substrate, which then was treated by hydrothermal reaction and finally modified with perfluorooctanoic solution. The phase constitution, microstructure, chemical composition, and wettability of the coating were investigated by X-ray diffractometer, scanning electron microscope, Fourier transform infrared spectrometer, and contact angle tester. Its mechanical stability, anti-adhesion behavior and corrosion resistance were also examined. The results show that the perfluorooctanoic was successfully grafted on the surface of coating consisted of petal-like CuO with micro-nano hybrid structure. The contact angle of water to the coating surface was161.24°, and the sliding angle was about 3°. Meanwhile, the as-prepared coating surface exhibits excellent mechanical stability, anti-adhesion behavior and corrosion resistance.
