Abstract

This application belongs to the technical field of polymer surface anti-icing. This application provides a magnetic polymer composite material with high-efficiency photothermal effect and its preparation method and application. By loading magnetic nanoparticles with one-dimensional quantum materials and arranging them radially close to the surface of the polymer material, a high photothermal effect is formed. The conversion efficiency functional surface realizes the dual functions of surface passive anti-icing and active photothermal deicing, improving the deicing efficiency. The polymer composite material of the present application is a three-dimensional composite material with a micro-nano structure, which has high geometric and dimensional stability and remarkable super-hydrophobic effect, overcomes the shortcomings of the surface hydrophobic anti-icing coating that is easy to fall off and easily damaged, and has poor anti-fouling properties. High wear resistance and service life. The preparation method provided by the application is simple in operation and low in cost, and the prepared magnetic polymer composite material with high-efficiency photothermal effect has broad application prospects in the fields of anti-icing, deicing, self-cleaning materials and the like.

Description

technical field [0001] The application belongs to the technical field of polymer surface anti-icing, and in particular relates to a magnetic polymer composite material with high-efficiency photothermal effect and its preparation method and application. Background technique [0002] Icing on transmission lines, composite insulators, and storage and transportation of cryogenic liquids can cause high energy consumption or major hazards to power infrastructure and transportation systems, and cause serious safety issues. De-icing and anti-icing are the two main methods used to improve icing conditions. At present, deicing methods mainly include mechanical deicing methods, heating deicing methods and chemical deicing methods. Although they are widely used, they are costly, seriously pollute the environment, and are easy to damage parts. Anti-icing methods include multi-scale surfaces such as coatings and geometric topologies, which are low-cost and environmentally friendly. Howe...
