Zif-8-based photothermal superhydrophobic anti-corrosion and anti-icing coating and preparation method thereof

Abstract

The present disclosure discloses a method for preparing a ZIF-8-based photothermal superhydrophobic anti-corrosion and anti-icing coating, including the following steps: S1: preparation of ZIF-8@PDA particles: synthesizing polydopamine modified ZIF-8@PDA particles in water in one step; and S2: preparation of ZIF-8-based photothermal superhydrophobic anti-corrosion and anti-icing coating: compounding the ZIF-8@PDA with a carbon material in a certain ratio for performing superhydrophobic modification, adding an adhesive, performing spraying on a surface of a substrate, and performing curing to obtain the ZIF-8-based photothermal superhydrophobic anti-corrosion and anti-icing coating. The ZIF-8-based photothermal superhydrophobic anti-corrosion and anti-icing coating material prepared in the present disclosure exhibits excellent superhydrophobicity, mechanical stability, and corrosion resistance. Also, the ZIF-8-based photothermal superhydrophobic anti-corrosion coating exhibits excellent passive delayed icing and active photothermal deicing capabilities on a surface of an aluminum alloy, and provides a novel strategy for deicing of industrial facilities and equipment in winter.
