Abstract

As a passive anti-icing strategy, properly designed superhydrophobic coatings can demonstrate outstanding performances. However, common preparation strategies for superhydrophobic coatings often lead to environmental pollution, high energy-consumption, high-cost and other undesirable issues. Besides, the durability of superhydrophobic coating also plagues its commercial application. In this paper, we introduced a facile and environment-friendly technique for fabricating abrasion-resistant superhydrophobic surfaces using thermoplastic polyurethane (TPU) and modified SiO2 particles (SH-SiO2). Both materials are non-toxicity, low-cost, and commercial available. Our methodology has the following advantages: use of minimal amounts of formulation, take the most streamlined technical route, and no waste material. These advantages make it attractive for industrial applications, and its usage sustainability can be promised. In this study, the mechanical stability of the superhydrophobic surface was evaluated by linear wear test. It is found that the excellent wear resistance of the superhydrophobic coating benefits from the characteristics of raw materials, the preparation strategy, and the special structure. In anti-icing properties test, the TPU/SH-SiO2 coating exhibits the repellency to the cold droplets and the ability to extend the freezing time. The electrochemical corrosion measurement shows that the as-prepared superhydrophobic surface has excellent corrosion resistance that can provide effective protection for the bare Q235 substrates. These results indicate that the TPU/SH-SiO2 coating possesses good abrasion resistance and has great potential in anti-corrosion and anti-icing applications.
