Design and Creation of Bioinspired Surfaces with Special Wettability
Bio-inspired smart materials should be a live material with various functions like organism in nature,they must have three essential elements as sense, drive and control. Our recent studies are focused on the design and fabrication of bio-inspired surfaces with special wettability based on these ideas. The 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. Considering the arrangement of the micro-and nanostructures, the surface structures of the water-striders legs were studied in detail. These results from the natural world provide a guide for constructing artificial super-hydrophobic surfaces and designing surfaces with controllable wettability. Accordingly,super-hydrophobic surfaces of aligned carbon nanotube films, aligned polymer nanofibers and differently patterned aligned carbon nanotube films have been fabricated. The large scale fabrications of super-hydrophobic polymer surfaces have been developed by modification of the traditional template method, the adoption of one-step coating and electrohydrodynamic processes respectively.
