Abstract

The invention belongs to the technical field of polymer surface anti-icing. The invention provides a magnetic polymer composite material with an efficient photothermal effect and a preparation methodand application thereof, magnetic nanoparticles are loaded with a one-dimensional quantum material and are radially arranged close to the surface layer of the polymer material to form a functional surface with high photothermal conversion efficiency; the dual functions of surface passive anti-icing and active photo-thermal deicing are achieved, and the deicing efficiency is improved. The polymer composite material provided by the invention is a three-dimensional composite material with a micro-nano structure, is high in geometric dimension stability and remarkable in super-hydrophobic effect,overcomes the defects that a surface hydrophobic anti-icing coating is easy to fall off, easy to damage and poor in antifouling property, and has relatively high wear resistance and relatively long service life. The preparation method thereof provided by the invention is simple to operate and low in cost, and the prepared magnetic polymer composite material with the efficient photothermal effect has a wide application prospect 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...
