A robust directional oil sliding surface is presented by utilizing re-entrant micro-groove arrays inspired from the microgrooves of rice leaf. The overhang micro-groove arrays are shown to provide two primary goals of "omniphobicty" and "anisotropic sliding" with DI water (γlv = 72.1 mN/m) as well as mineral oil (γlv = 28 mN/m) and conventional photoresist.
提出了一种稳健的定向油滑动表面,该表面受到稻叶微槽启发的倒圆微槽阵列的启发。研究表明,悬垂微槽阵列具有“超疏油性”和“各向异性滑动”这两个主要目标,其应用的液体包括去离子水(γlv = 72.1 mN/m)、矿物油(γlv = 28 mN/m)和常规光刻胶。
