We demonstrate the fabrication of 2-D arrays of nanopillars made from perfluoropolyether derivatives using a porous anodic aluminum oxide membrane as a template. Pretexturing the aluminum prior to anodization enables one to engineer multiple morphological length scales and thereby synthesize a lotus-leaf-like topography. Both nanopillars on a flat surface and on a lotus-leaf-like topology exhibit superhydrophobicity, low contact angle hysteresis, and self-cleaning.
我们展示了使用多孔阳极氧化铝膜作为模板，由全氟聚醚衍生物制成的纳米柱二维阵列的制造方法。在阳极氧化之前对铝进行预纹理化处理，能够设计多种形态长度尺度，从而合成出荷叶状的形貌。无论是平面上的纳米柱还是荷叶状拓扑结构上的纳米柱，都表现出超疏水性、低接触角滞后和自清洁性能。
