Problems solved by technology

Therefore, the combination of active deicing and passive anti-icing has become a current research hotspot, such as the literature Integration of Self-Lubrication and Near-Infrared Photothermogenesis for Excellent Anti-Icing / Deicing Performance, Adv.Funct.Mater 25(2015)4237- 4245, Passive Anti-Icing and Active Deicing Films, ACS Appl. Mater. Interfaces 8 (2016) 14169-14173 and Superhydrophobic SiC / CNTs Coatings with Photothermal Deicing and Passive Anti-Icing Properties, ACS Appl. Mater. Interfaces 10 (2018) 36505 -36511, but the photothermal coatings in these studies will be lost to varying degrees during use, which directly affects their photothermal conversion efficiency, thereby reducing the photothermal deicing efficiency
In the research so far, there is no research on treating the substrate itself to make it have photothermal properties. This method can avoid the phenomenon of coating loss and photothermal weakening.
Therefore, the technology of preparing anti-icing coatings for photothermal deicing still needs to be improved.

Abstract

The invention belongs to the technical field of material surface engineering, and relates to an anti-icing coating and an anti-icing material, and preparation methods thereof. The preparation method of the anti-icing material comprises the following steps: putting a base material into iodine steam, carrying out adsorption treatment, then spraying the anti-icing coating on the base material subjected to adsorption treatment, and drying to obtain the anti-icing material. The photothermal effect of iodine is introduced into the field of icing prevention for the first time, the base material treated by the iodine steam has excellent photothermal characteristics, and the temperature can be rapidly increased and heat is rapidly emitted under the irradiation of near-infrared light (700-1100 nm),so that an ice layer on the surface is gradually molten, and an ice-water mixture in a semi-molten state can easily slide off from the surface due to the water repellency characteristic of a rough structure of the surface, active photothermal deicing and passive icing prevention are combined, and the anti-icing efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of material surface engineering, and relates to an anti-icing coating, an anti-icing material and a preparation method thereof. Background technique [0002] In cold regions, the formation and accumulation of ice on objects is a natural phenomenon that can be seen everywhere, but this natural phenomenon also has a serious impact on our lives, such as icing on roads, power transmission lines, aircraft, optical components, etc. Inconvenience to us. Therefore, in these areas, we have to investigate how to reduce the formation of ice or make it easier to remove ice on these surfaces to mitigate the negative effects of icing. There are many anti-icing measures in real life, mainly divided into active anti-icing and passive anti-icing. [0003] The application of superhydrophobic materials to anti-icing has been widely reported. The superhydrophobic properties of the coating can reduce the possibility of water s...
