▎ 摘　　要

NOVELTY - Multifunctional multi-level nano-cone array structure coating with multi-band compatible hiding and super-hydrophobic characteristics comprises coating surface is a non-flat convex structure, the bottom of coating is provided with an upward convex MXene or polyaniline nano-array layer, the upper part of the coating is a resin layer, and the upper surface of MXene and polyaniline nanosheet is set with a secondary nano structure fixed by resin. The second-level nanosructure is B granule whose surface is set to A particles. The A particles and the B particles are surface functional A particles and surface functional B particles. The first particles are nano-carbon black particle or carbon nano tube powder or graphene powder. The B particles are nanosilica particles or nano-ceramic particles or nano resin particles. USE - The multifunctional coating with multi-band compatible hiding and super-hydrophobic characteristics is used in wind blade, high-speed train bogie and high speed aircraft field (claimed). Can also be used for weapon. ADVANTAGE - The method is simple in operation, low in cost, high in preparation efficiency, capable of realizing super-hydrophobic, anti-icing, multi-band stealth, radiation ultraviolet resistance flexibility, impact resistance and wear resistance and other multifunctional compatibility. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation method of coating, by constructing MXene or polyaniline nano-array on the surface of the substrate by using the directional freeze-drying technology, carrying out surface functionalization treatment to the A particle and B particle by using the surfactant and corresponding solvent to realize self-assembly composite of the two to form a secondary nano structure, mixing the second-level nano structure in the resin and the MXene or polyaniline nano array are compounded to form a multifunctional coating with multi-frequency band invisible body and super-hydrophobic characteristics using the temperature-changing vacuum dipping method.
