摘要
The phenomenon of surface ice accumulation in low temperature and high humidity environments brings significant challenges to economy, energy, and security. Superhydrophobic surfaces with micro-nano structures are considered as effective anti-icing surfaces. However, deicing can damage the micro-nano structures and increase the ice adhesion strength. Herein, a low-adhesion, superhydrophobic photothermal response coating was introduced by combining micro-nano surface and lubricated surface, which exhibits low adhesion self-healing photothermal de-icing performance. The surface temperature rises rapidly to 85 °C under 1 solar irradiation and the frozen droplet can melt within 150 s. The prepared coating has a contact angle of up to 162° and a rolling angle as low as 4.8°. The superhydrophobicity enabled the coating to have excellent anti-icing property with icing delay times up to 596 s. Ice and frost layers on the coating surface can melt and fall off illuminating with light. In addition, beeswax as phase change materials contributes to the coating's efficient self-healing properties. The coating can restore its excellent superhydrophobicity and surface morphology quickly via a simple heat treatment after suffering chemical and mechanical damage. The coating design strategy will provide inspiration for natural solar photothermal anti-icing surfaces and engineering applications.
