Abstract：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.
