摘要
对荷叶及水稻叶的研究结果表明 :微米与纳米相结合的结构不仅可以产生较大的接触角 ,而且可以产生较小的滚动角 ;微米结构在表面的排列可以影响水滴的运动趋势。以这些从自然界获得的结果作为理论依据 。
Superhydrophobic surfaces giving contact angle (CA) with water greater than 150°, are attractive for both fundamental research and practical applications. Recent studies on lotus and rice leaves reveal that a super-hydrophobic surface with both large CA and small roll angle (α) needs the incooperation of micro-and nano-structures, and the arrangement of microstructures on the surface can influence the motion tendency of water droplets. These results from natural world give a guide in artificially constructing superhydrophobic surfaces and designing for controllable wettability. Accordingly, superhydrophobic surfaces of polymer nanofibers and aligned carbon nanotube (ACNT) films with various array structures are created.
