摘要

超疏水微纳结构表面广泛应用于自清洁、防冰、抗菌、柔性传感等领域，但其制备工艺仍面临一定的挑战. 以阳极氧化铝(AAO)膜为模板，采用热压印在聚丙烯(PP)表面成型了规整的纳米结构阵列. 对纳米结构阵列进行超声处理，在超声空化作用下，PP表面纳米结构转变为类花瓣状微纳结构. 结果表明，经超声处理后的微纳结构PP表面的接触角从152.3°上升至160.0°，滚动角从11.5°降低至1.8°，表面黏附力从75 μN降低至38 μN，呈现典型的超疏水低黏附特性且其自清洁效应明显. 采用模板法与超声辅助相结合的方法制备超疏水微纳表面具有方便快捷、成本低廉、效果显著的优点，有望应用于工业生产领域.

Abstract

Superhydrophobic micro-/nanostructured surfaces are widely used in the fields of self-cleaning

anti-icing

anti-bacterial and flexible sensor

but there are still some challenges in the preparation methods of these surfaces. In this work

the polypropylene (PP) surfaces with nanostructure arrays were prepared using the hot compression molding with anodic aluminum oxide (AAO) templates. With the ultrasonic-assisted treatment

the nanostructure was transformed onto micro-/nanostructure due to the ultrasonic cavitation effect. The superhydrophobic property of micro-/nanostructured surface was improved after ultrasonic treatment

the contact angle increased from 152.3° to 160.0°

the rolling angle decreased from 11.5° to 1.8°

and the surface adhesion decreased from 75 μN to 38 μN. Moreover

the self-cleaning performance of the micro-/nanostructured PP surface was also better than that of the nanostructured PP surface. The template method combining with the ultrasonic-assisted treatment is convenient

cheap

and effective in the preparation of superhydrophobic micro-/nanostructured surfaces

expecting promising applications in industrial production.
