Research Progress of Preparation Technology of Magnesium Alloy Superhydrophobic Surface

超疏水表面因其在日常生活及工农业生产等领域有巨大的应用前景而受到科研人员的广泛关注。基于镁及其合金基底超疏水表面的制备研究可以加深对材料特性的认识、扩展材料应用范围和提高材料应用性能而具有重要的意义。介绍了超疏水表面的相关理论基础和超疏水状态下的两类模型及其相互关系,对两类模型下表面微细结构和固体表面化学成分对接触角的影响进行了讨论。从构建超疏水表面的两种途径出发,一是在低表面能物质上构建特殊微细结构,二是在微细结构表面利用低表面能物质进行修饰,着重总结归纳了镁合金基底超疏水表面制备技术的研究进展,并对镁合金超疏水表面的发展进行了展望。

Superhydrophobic surface with non-wetting and self-cleaning properties has raised considerable concern for its vast application prospect. Preparation study of superhydrophobic surface on magnesium and its alloy is of great significance to deepen understanding of material characteristics, expand the application scope of materialss and improve application performance of materials. Relevant theoretical basis of superhydrophobic surface as well as two models in superhydrophobic state and their relationship were presented. In addition, effects of surface fine structure and solid surface chemical composition on contact angle were discussed. By exploring two constitution approaches of superhydrophobic surface： constituting special fine structure on substances of low surface energy and modifying fine structure surface by using substances of low surface energy, research progress of preparation technology of superhydrophobic surface on the substrate of magnesium alloy was summarized emphatically, and the development of superhydrophobic surface was expected.
