Multifunctional multi-stage nanocone array structure coating with multi-band stealth and super-hydrophobic characteristics and preparation method of multifunctional multi-stage nanocone array structure coating

Abstract

The invention discloses a multifunctional multi-stage nanocone array structure coating with multi-band compatible stealth and super-hydrophobic characteristics and a preparation method of the multifunctional multi-stage nanocone array structure coating. A nanocone array formed by self-assembly of MXene is constructed by using a directional freeze drying technology, and nano carbon black and nano silicon dioxide are subjected to surface functionalization treatment by using a surfactant; the preparation method comprises the following steps: uniformly mixing treated powder in a solvent to realize self-assembly of a two-stage nanostructure, uniformly mixing the composite powder with a resin matrix by adopting a mechanical stirring process, and compounding prepared slurry with an MXene nanocone array by adopting a variable-temperature vacuum impregnation method to obtain the coating with the multi-stage nanocone structure. The preparation method is easy to operate, low in cost and high in preparation efficiency, and compatibility of multiple functions such as super-hydrophobicity, ice prevention and removal, multi-band stealth, ultraviolet radiation resistance, flexibility, impact resistance and wear resistance can be achieved at the same time. The problems that an existing hydrophobic coating is low in anti-icing and deicing efficiency, incompatible in multi-band stealth and durable in outdoor environment can be solved.

Description

technical field [0001] The invention belongs to the technical field of multi-functional coating preparation, in particular to a multi-functional multi-level nano-cone array structure coating with multi-band stealth and super-hydrophobic properties and a preparation method thereof. Background technique [0002] With the rapid development of science and technology, the application of hydrophobic coatings is becoming more and more extensive, and the requirements for hydrophobic coatings in various fields are also increasing. For example, large wind blades and high-speed train bogies need to be coated with a hydrophobic coating to obtain good anti-icing and deicing effects to ensure the normal operation of wind blades and trains. In addition, aircraft or weapons with high maneuverability not only need to have good multi-band stealth performance, including radar stealth, infrared stealth, visible light stealth, etc., but also work in the open air for a long time during the above-...

AI Technical Summary

Problems solved by technology

But once a thin layer of ice appears on the surface of the coating, the freezing speed increases rapidly and the coating basically does not have self-deicing ability

Even though some hydrophobic coatings can be deiced by electric heating, the large amount of energy consumed by pure electric heating is not in line with the current development trend of energy saving and environmental protection

On the other hand, because the realization of multi-band stealth has many restrictions on materials, such as meeting radar impedance matching, special absorber components, multi-layer structures, etc., these are likely to have a negative impact on the hydrophobic performance of the coating, so the current hydrophobic coating layer can not effectively realize the compatibility of multi-band stealth performance and hydrophobic performance
