Polymer micro/nano hierarchical structures were successfully formed by photo-nanoimprinting using anodic porous alumina molds. Anodic porous alumina molds with hierarchical structures were prepared by the anodization of an Al substrate with a micro-concave array. The obtained surfaces with hierarchical structures exhibited superhydrophobicity. The hydrophobic properties of the obtained samples were dependent on the surface structures and could be optimized by changing the micro- and nanopatterns in the hierarchical structure.
通过使用阳极多孔氧化铝模具进行光纳米压印,成功地形成了聚合物微/纳分级结构。具有分级结构的阳极多孔氧化铝模具是通过对具有微凹阵列的铝基板进行阳极氧化制备的。所获得的具有分级结构的表面表现出超疏水性。所获得样品的疏水性能取决于表面结构,并且可以通过改变分级结构中的微图案和纳米图案来进行优化。
