仿生超疏水表面研究进展

Research Advanced of Bioinspired Superhydrophobic Surface

对植物叶表面的研究结果表明:微米与纳米相结合的结构可以产生较大的接触角和较小的滚动角。表面化学组成与粗糙结构相结合成为仿生超疏水表面的重要特点。本文在总结近年来仿生超疏水表面的最新研究成果的基础上,着重分析和讨论了仿生超疏水表面的物理机制、制备方法、超亲水与超疏水的转换,并探讨了这一领域的发展方向。

Recent studies on plant leaves reveal that a superhydrophobic surface with both larger contact angle and smaller roll angle needs the incooperation of micro-and nano-structures.The cooperation between the surface chemical compositions and the rough structure is crucial to construct superhydrophobic surface.The physical basis of the superhydrophobicity,artificial synthesis of the superhydrophobic surface and the responsive switching between superhydrophilicity and superhydrophobicity were reviewed,and the developmental direction in future were also discussed.
