海上溢油是一个严重的全球性环境问题。具有可控润湿性的智能材料在油水相关应用中具有全球性的挑战性兴趣。大自然提供了一个具有化学成分的显着层次结构的通用平台，为解决许多挑战提供了生物启发的解决方案。在这项研究中，一种方法来实现强大的超疏水/疏油性能的柔性聚二甲基硅氧烷（PDMS）表面，模仿自然荷叶表面的层次形态。该结构是通过水热组装氧化锌纳米棒到微结构表面上制备的，这导致了水下超疏油表面，其油接触角高达153°，可以有效地防止表面被油污染。我们的研究结果对学术研究和工业应用具有重要意义，并可能对科学领域产生创新影响。
Oil spills at sea are a severe global environmental issue. Smart materials with controllable wettability are of global challenging interest in oil–water related applications. Nature offers a versatile platform of remarkable hierarchical structures with a chemical component, which provides bioinspired solutions for solving many challenges. In this study, an approach to achieve robust superhydrophobic/oleophobic property on flexible polydimethylsiloxane (PDMS) surfaces which mimics the hierarchical morphology of the natural lotus leaf surface is shown. The structure is prepared by hydrothermal assembly of zinc oxide nanorods onto the microstructured surface, which results in an underwater superoleophobic surface with an oil contact angle up to 153° which can effectively prevent the surface from being polluted by oils. Our results are significant in terms of their importance to academic research and industrial applications and may lead to an innovative impact in the science field.
