Grid-structured ZnO microsphere arrays assembled by uniform ZnO nanorods were fabricated by noncatalytic chemical vapor deposition, taking advantage of morphologies of alumina nanowire pyramid substrates and ZnO oriented growth habits. Every ZnO microsphere (similar to the micropapilla on a lotus leaf surface) is assembled by over 200 various oriented ZnO nanorods (similar to the hairlike nanostructures on mircopapilla of a lotus leaf). This lotus-leaf-like ZnO micro-nanostructure films reveal superhydrophobicity and ultrastrong adhesive force to liquid. The realization of this hierarchical ZnO nanostructure film could be important for further understanding wettability of biological surfaces with micro-nanostructure and application in microfluidic devices.
利用氧化铝纳米线金字塔衬底的形貌和氧化锌的取向生长习性，通过非催化化学气相沉积法制备了由均匀氧化锌纳米棒组装而成的网格结构氧化锌微球阵列。每个氧化锌微球（类似于荷叶表面的微乳头）由200多个不同取向的氧化锌纳米棒（类似于荷叶微乳头的毛发状纳米结构）组装而成。这种荷叶状氧化锌微纳米结构薄膜具有超疏水性和对液体的超强粘附力。这种分级氧化锌纳米结构薄膜的实现对于进一步理解具有微纳米结构的生物表面的润湿性以及在微流控装置中的应用可能具有重要意义。
