摘　　要：浸润性是固体表面的重要特征之一,它是由表面的化学组成和微观几何结构决定的。日前我们关于荷叶和水稻叶的研究显示,一种具有较大接触角和较小滚动角的超疏水表面,需要微米和纳米级的结构有机结合形成复合结构,而且表面微观结构的排列方式会影响水滴的运动趋势。通过对水黾腿表面结构的详细研究,得到了超疏水性质与微、纳米结构取向之间的关系。据此,我们已成功制备出了超疏水和超双疏的纳米界面材料,并实现了热响应性和光响应的超疏水与超亲水可逆“开关”材料。The wettability of solid surfaces is a very important property, and is governed by both the chemical composition and geometrical microstructure of the surface. Our recent studies on lotus and rice leaves reveal that a super-hydrophobic surface with both a large CA and small sliding angle needs the cooperation of micro and nanostructures, and the arrangement of the microstructures on this surface can influence the way a water droplet tends to move. The study on the surface structures of the water-strider's legs reveals the relationships between super-hydrophobicity and orientation of the micro and nano-scale composite structures. Accordingly, super-hydrophobic and super-amphiphobic nano-scale interface materials have been successfully prepared and the reversible switcher materials on super-hydrophobicity and super-hydrophilicity have been realized.
