Abstract

The invention relates to a coat material rapidly cross-linking under the irradiation of ultraviolet and simultaneously containing a POSS component and an azide reaction group, and concretely relates to a POSS acrylate / p-vinylbenzylazide copolymer coat material and its preparation method. Free radical copolymerization of a polyhedral oligomeric silsesquioxane-containing (meth)acrylate monomer and an azido group-containing styrene monomer is carried out, the obtained copolymer is dissolved in a solvent to form a dispersion, and ultraviolet irradiation and solvent volatilization are carried out to obtain a coat having a good stability and a high adhesion. According to the invention, the azido group decomposes to a nitrene group having an extremely-high reaction activity under the irradiation of the ultraviolet, and the nitrene group can almost react with any C-H bonds or C=C bonds of an adjacent molecule, and can even be inserted into a O-H bond or an N-H bond, so the chemical modification of the surface of glass and a cotton fiber or a film in covalent bond is realized, and the process is simple and rapid.

Description

technical field [0001] The invention belongs to the technical field of coating materials and surface modification, and relates to a POSS acrylate / p-vinylbenzyl azide copolymer coating material and a preparation method thereof, in particular to a coating material containing POSS components and capable of passing through an azide group. A group of rapidly cross-linked surface-modified materials. Background technique [0002] Polyhedral Oligomeric Silsesquioxane (Polyhedral Oligomeric Silsesquioxane, referred to as POSS) is a kind of organic / inorganic hybrid molecule with a cage structure, which has superhydrophobicity, large steric hindrance effect and nanoscale. With the diversification of monomer structure and its nanoscale size, it is hoped to build new materials, so that it has good thermal properties, mechanical properties, oxidation resistance, etc., thereby expanding the new properties and new applications of POSS in functional materials . [0003] The azide group is ...
