Abstract
Photothermal superhydrophobic surfaces are prospective to become ideal anti−/de-icing surfaces because of their icing delay and rapid photothermal deicing property. Herein, a universal photothermal superhydrophobic composite coating (PSCC) was robustly sandwiched a photothermal layer based on hydrophobically modified titanium nitride (TiN) composite spherical nanoparticles (TiN@SiO2@OTES) between polydimethylsiloxane (PDMS) double layers (the top layer acting for protection and the bottom for thermal insulation and adhesion with the substrate). Due to the high photothermal conversion efficiency (66.0 %) of TiN nanoparticles, the composite coating demonstrated a satisfactory anti−/de-icing efficiency with a stable icing delay time (690 s at 1 sun and − 10 °C) and a fast photothermal de-icing capability (120 s under 1 sun and − 10 °C). In addition, the coating could maintain super-hydrophobicity exhibiting good durability and stability in the lash of sand and water due to the multi-layer design reinforced by PDMS, which was also favorable for residue-free removal of surface to achieve the self-cleaning. Overall, the robust corrosion-resistant photothermal superhydrophobic coating showed a potential for anti−/de-icing application.
