Robust superhydrophobic coating and the anti-icing properties of its lubricants-infused-composite surface under condensing condition

Abstract

Superhydrophobic surfaces (SHS) are accessible by means of incorporating a micro- or nano-structured low-energy surface that creates an air layer beneath water droplets. However, poor stability towards abrasion, low temperatures, and chemical corrosion have hindered their wide application. In our study, a SiO2–UHMWPE (ultra-high molecular weight polyethylene)-based SHS that could resist severe abrasion, multiple tape peelings, water dripping, and corrosion upon exposure to strong chemical agents was fabricated. However, the water droplets were pinned on the prepared SHS at low temperatures (below 0 °C) due to ice/water capillary bridges. To overcome this problem, slippery liquid-infused porous surfaces (SLIPSs) were prepared by infusing different lubricants into the SHSs, and the water droplets smoothly travelled under the conditions of low temperatures, suggesting superior anti-icing properties. Moreover, the travelling speed of water droplets on the prepared SLIPSs was restrained under the conditions that favored the condensation of atmospheric humidity.
