摘要
采用盐酸水溶液化学刻蚀和水热反应的方法在锌基体上构建微纳米粗糙结构,再经全氟辛酸修饰,制备疏液表面。通过X射线衍射仪、扫描电镜、红外光谱仪和接触角测量仪对试样表面的相组成、微观形貌、化学成分及润湿性进行表征。结果表明:试样的亚微米结构表面生长出一层ZnO纳米棒,在低表面能物质的共同作用下表现出良好的抗水流冲击性和稳定性。当盐酸浓度为1.0mol/L,水热反应温度为95℃时,ZnO纳米棒的生长形态最优,水和花生油在疏液表面的最大接触角分别为154.65°和144.65°,滚动角小于10°。
Micro-nano structure on zinc substrate was fabricated through the combination of chemical etching with hydrochloric acid aqueous solution and hydrothermal reaction.After modification with perfluorooctanoic solution,the lyophobic surface was prepared.The phase composition,microstructure,chemical composition,and wettability of the as-obtained surface were investigated by X-ray diffractometer,scanning electron microscope,Fourier transform infrared spectrometer,and contact angle tester.The results show that a layer of ZnO nano-rods grows on the surface of the submicrometer structure,and exhibits good resistance to water impact and stability under the combined action of low surface energy material.When hydrochloric acid concentration is 1.0 mol/L and hydrothermal reaction temperature is 95℃,the lyophobic surface possesses the best morphology of ZnO nano-rods.The maximum contact angles of distilled water and peanut oil are 154.65°and 144.65°,respectively,and the sliding angle is less than 10°.
