通过水热合成法构筑微纳结构,结合表面化学改性,成功地在铝片基底载体上制备了一种新型的超疏水涂层。稀土氧化铈的加入使得表面结构不仅均匀分布,材料表面也展现出超强排斥性,静态接触角可达到160˚,同时滚动角不超过5˚。水热合成法制备的特殊浸润性界面材料,可以通过调节水热法的工艺持续获得,且该材料在多种恶劣环境中均表现出较好的超疏水稳定性,对于疏水材料的大规模生产和应用都具备非常重大的借鉴意义。
A novel type of super-hydrophobic coating was successfully prepared on the aluminum sheet sub-strate via hydro-thermal synthesis methods combined with chemical modification. The addition of cerium oxide supplies the surface not only well distributed structures, but also unparalleled su-per-repellency, the static water contact angle could reach 160˚, and the rolling angle is not less than 5˚. The special wetting materials prepared by hydro-thermal synthesis can be continuously ob-tained by the process of regulating hydro-thermal method, and the materials show good su-per-hydrophobicity in a variety of harsh environments, which is of great reference significance for the large-scale production and application of hydrophobic materials.
