我们提出了一种简便、低成本、快速的方法，在钢基材上制备水接触角和菜籽油接触角分别为160度和153度的超双疏表面。其制备过程包括磷化槽中磷酸盐、铜的共沉积以及1H,1H,2H,2H-全癸基三异丙氧基硅烷(FAS-17)对低表面能材料的改性。通过接触角测量、X射线衍射、扫描电子显微镜（配备能谱仪、X射线光电子能谱仪和电化学工作站）研究了表面润湿性、化学成分、形貌和防腐性能。结果表明，表面实现超双疏的最佳CuSO4中心点5H(2)O浓度为6 g L-1，制备的表面在600目SiC砂纸上表现出优异的机械耐磨性能。此外，动态结霜-除霜实验表明，表面具有良好的抗结霜能力。动电位极化证明超疏水表面可以保护钢基体免受腐蚀溶液的影响。同时表面在不同pH值下也表现出良好的化学稳定性，在泥水和润滑油中均表现出优异的自洁能力。
We present a facile, low-cost, and fast method for preparing superamphiphobic surface with water contact angle and rapeseed oil contact angle of 160 degrees and 153 degrees on steel substrate. The fabrication process is composed of the phosphate, Cu co-deposition in phosphating bath and the low surface energy materials modification by 1H,1H,2H,2H-peruorodecyltriisopropoxysilane (FAS-17). Contact angle measurement, X-ray diffraction, scanning electron microscopy equipped with energy-dispersive spectrometry, X-ray photoelectron spectroscopy, and electrochemical workstation were carried out to investigate the surface wettability, chemical composition, morphology, and anti-corrosion performance. Results show that the optimal CuSO4 center dot 5H(2)O concentration for the surface to achieve superamphiphobicity is 6 g L-1, and the prepared surface exhibits excellent mechanical abrasion resistance on 600 grit SiC sand paper. Moreover, the dynamic frosting-defrosting experiments indicated that the surface has a good anti-frosting ability. The potentiodynamic polarization proves that the superhydrophobic surface can protect the steel substrate from corrosion solution. Meanwhile the surface also shows a good chemical stability under different pH values and excellent self-cleaning ability in both muddy water and lubricating oil.
