Polymer surfaces comprising nanopillars with various geometries were prepared by nanoimprinting the surface using anodic aluminium oxide templates. In particular, a simple fabrication method for long-neck vase-like stepped nanopillars was established, and the surface showed considerable enhancement in the water contact angle, for example from 95.7° to 150.6° for the polystyrene surface. This enhanced hydrophobicity could be explained by the desirable reduction in the area of the solid-liquid interface and reduced sticking between the nanopillars.
聚合物表面包含各种几何形状的纳米柱，通过使用阳极氧化铝模板对表面进行纳米压印来制备。特别地，建立了一种用于长颈花瓶状阶梯纳米柱的简单制造方法，表面的水接触角得到了相当大的提高，例如聚苯乙烯表面从 95.7°提高到 150.6°。这种增强的疏水性可以通过理想地减少固液界面的面积和减少纳米柱之间的粘连来解释。
