Abstract

The invention relates to a method for initiating a graft polymer through ultraviolet induction on the surface of glass, belonging to the technical field of surface modification of the glass. The method comprises the following steps of: uniformly coating a prepared reaction solution on the surface of the glass treated by a silane coupling agent, and placing the glass in an ultraviolet light curing machine to irradiate the glass for 3min, thereby obtaining a sheet glass sample, the surface of which is fixed with a polymer chain. The method has the advantages that an operating technology is simple, the grafting effect is obvious, and raw materials used are commercially available, can be used without needing to be subjected to a complex purification process and are low in cost and easily obtained; graft polymerization is initiated through ultraviolet induction, the operation is simple, the reaction time is short, and the environmental pollution is low; and the method can be used for the reinforcement of adhesive property between resin in a reinforced material and the glass and the modification of the surface character of the glass and has wide industrial application prospect.

Description

technical field [0001] The invention belongs to the technical field of glass surface modification, relates to a glass surface grafting method, in particular to a method for initiating free radical polymerization and grafting polymer chains on the glass surface through ultraviolet-induced redox. Background technique [0002] Graft polymerization modification on the surface of inorganic materials can produce many new properties, such as amphiphilicity, chemical activity, dispersibility, adsorption and compatibility. Silicon-based materials, such as glass, nano-SiO 2 etc. Due to its excellent performance and relatively low price, it has become the preferred matrix for the preparation of polymer / inorganic hybrid composites. [0003] At present, the grafting techniques reported in domestic and foreign literature mainly include: (1) grafting by atom transfer radical polymerization (ATRP). Bottcher et al. (Buttcher H, Hallensleben M L. ATRP grafting from silica surface to create ...
