Abstract

The invention discloses super-lyophilic coating resistant to mechanical damages. The super-lyophilic coating comprises at least three layers of coating structures, which are sequentially stacked; thefirst layer is a coating close to a substrate, and the next coating is sequentially stacked on the last coating; the first layer is made of low-molecular-weight polymer which is mixed with inorganic nano particles with amount 0-2 times that of the low-molecular-weight polymer; the second layer and each next layer are made of high-molecular-weight polymer which is mixed with inorganic nano particles with amount 0-2 times that of the high-molecular-weight polymer; and the polymer of each layer is a hydrophilic polymer material. The coating adopts a multi-layer bionic laminated layer, the bottom,close to the substrate layer, of the coating is made of low-molecular-weight polymer, and the coating is good in bonding force with the substrate layer; a plurality of high-molecular-weight polymer film layers are sequentially assembled in sequence, so that the super-lyophilic coating has very good bonding force; and the structures buffer with each other, has good toughness, so that the super-lyophilic coating is not liable to damage under action of mechanical friction damages.

Description

technical field [0001] The invention belongs to novel lyophilic materials, in particular to a super-lyophilic coating resistant to mechanical damage and a preparation method thereof, and belongs to the technical field of functional coatings. Background technique [0002] Super-lyophilic materials refer to the excellent wetting ability of water-based or oily droplets on the surface of the material, usually the contact angle of the droplets is less than 10°, so the water-based or oily droplets are easy to adhere to the surface, so that the material surface can be self-cleaning , or the functional coating is easy to level and wet on its surface to prepare a functional coating with excellent surface properties, which is conducive to improving the smoothness and smoothness of the surface of the material. In addition, since the surface of superlyophilic materials usually has functional reactive functional groups with high surface energy, it can provide a universal functional coati...
