Problems solved by technology

In general, these functions of the material are short-term, because the usual hydrophilic material has strong water solubility, and the hydrophilic material is easy to lose after absorbing water. In addition, the long-term maintenance of high moisture in the material is very important for the material itself. It is also quite unfavorable; and materials with good hydrophobicity generally have certain lipophilicity, and the surface resistance will be relatively large. down, the practicality is not very high

Abstract

The invention discloses a functional composition which is characterized by comprising temperature-sensitive macromolecules, a photo-curing material and a photoinitiator. By using the hardness and the scratching resistance of a functional coating layer prepared by the composition, the durability and the use range of the coating layer can be effectively improved; furthermore, the functional coating layer and the temperature-sensitive macromolecules achieve a good supplementary effect, and the original characteristics of the temperature-sensitive macromolecules are kept.

Description

Technical field [0001] The invention involves a function composition, especially a function composition that can form surface wetness that can change the surface with temperature. Background technique [0002] Temperature -sensitive polymer is a category of high -molecular materials that can cause reversible changes with temperature changes with temperature changes.Common temperature-sensitive polymers include polymers of methyl acrylic N, N-di methyl ethyl ester, common polymer of N-isopropyl acrylamide, and cluster, temperature-sensitive shell polysaccharides, and so on.Pharmaceutical sustained release, material separation, memory switch and other aspects are becoming more and more widely used.In this patent, the minimum critical dissolution temperature of the temperature -sensitive polymers (LCSTEMPERATURATUR (LCST) refers to the water -soluble polymer or part of the water -soluble polymer material at a certain temperature, but in the water, it is large in water, and it is mor...
