采用化学刻蚀的方法在铝合金基体上构筑出微纳米结构,并用乙基三氯硅烷进行硅烷化处理,制备出具有超疏水性质的表面。水滴与表面的接触角可以达到159° ,滚动角> 1° 。用扫描电子显微镜(SEM)和X-光电子能谱(XPS)分别对所制备表面的形貌和元素进行了分析。同时,考察了溶液浓度,修饰时间以及相对环境湿度对表面疏水效果的影响,并且考察了不同pH值水溶液在其表面的接触角。另外,对所制备的超疏水表面的稳定性和抗腐蚀性能也进行了测试。结果表明:浓度为1.0mol/L,反应时间2.5h,环境湿度40%~55%是最佳的制备条件。该条件下制备的超疏水表面具有良好的稳定性和抗腐蚀性能。 |

The aluminum alloy surfaces with micro-and nanostructures were fabricated by chemical etching method. After modification with ethylsilicone, the as-prepared surfaces show super-hydrophobic properties with a water contact angle of up to 159° and sliding angle of smaller than 1°. The images and elements of the as-obtained surfaces were investigated by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS), respectively. Meanwhile, the effects of the solution concentration, reaction time and relative humidity on the super-hydrophobicity were investigated, as well as the relationship between contact angle and pH value of the solution was studied. Moreover, the stability and corrosion resistance of the super-hydrophobic surfaces were also tested. The results show that the optimal preparation conditions are 1.0 mol/L of ethylsilicone solution concentration, 2.5 h of reaction time and 40%~55% of relative humidity. And all the as-prepared super-hydrophobic surfaces show long time stability and corrosion resistance. |
