ABSTRACT

Solid/liquid interface drag reduction is a hot topic and it is of great significance to reduce energy consumption in industrial field. Herein, we prepare a slippery liquid-infused porous surface (SLIPS) with excellent self-healing and super-slippery properties. Through adjusting the density of Zn-Al LDH films on aluminium foil, the ability of rough surface to capture lubricant oil is studied. The SLIPS can repel various liquids such as water, white mineral oil and ethanol. By testing the friction of solid/liquid interface, the drag reduction ratio of SLIPS is 20–30% to water, 10–20% to white mineral oil and 8–12% to ethanol at low velocity. We believe the SLIPS has great potential application in solid/liquid interface drag reduction.

在光滑的注入液体的多孔表面上用不同的液体减阻

摘要

固/液界面减阻是一个热门话题,在工业领域降低能耗具有重要意义。在此,我们制备了一种光滑的液体注入多孔表面 (SLIPS),具有出色的自愈性和超滑性能。通过调节铝箔上Zn-Al LDH薄膜的密度,研究了粗糙表面捕获润滑油的能力。SLIPS 可以排斥各种液体,如水、白矿物油和乙醇。通过测试固/液界面的摩擦,SLIPS在低速时对水的减阻率为20-30%,对白矿物油为10-20%,对乙醇为8-12%。我们相信 SLIPS 在固/液界面减阻方面具有巨大的应用潜力。
