Abstract

The invention relates to the technical field of new materials, and provides a preparation method of a flexible anti-covering / deicing coating fabric, which comprises the following steps: preparing a carbon precursor solution, adding a proper amount of a surfactant and a template material which can be removed in a later period, carrying out hydrothermal reaction for a period of time, filtering, washing, drying, putting the obtained solid powder into a tubular furnace, and carrying out high-temperature pyrolysis, thereby obtaining the flexible anti-covering / deicing coating fabric. A hollow carbon material is obtained; mixing an adhesive and a curing agent, coating the surface of the fabric, and curing to obtain a pretreated fabric; and preparing a hollow carbon material suspension dispersion liquid, uniformly spraying the hollow carbon material suspension dispersion liquid on the surface of the pretreated fabric, and curing to obtain the flexible anti-covering / deicing coating fabric. The textile material is used as the substrate, the hollow carbon material with high specific surface area and low density is used as the photo-thermal substrate, the hydrophobic effect is good, and the advantages of passive icing prevention and active photo-thermal deicing are achieved. The carbon coated fabric provided by the invention has the advantages of super-hydrophobicity, good photothermal effect, good durability, strong adhesive force, recyclability, long service life and environmental protection.
