Abstract

The invention relates to a method for rapid preparation of an organic-inorganic hybrid porous integral material based on photoinduced thiol-ene polymerization reaction. Specifically, the method includes: mixing a tetravinyl compound (functional monomer), a multi-mercapto compound (functional monomer), a pore-forming agent and a photoinitiator and conducting ultrasonic dissolution, then carrying out photoinduced thiol-ene polymerization reaction under the irradiation of an ultraviolet lamp with certain wavelength, thus obtaining the porous organic-inorganic hybrid integral material by one step. The preparation method has the advantages of mild conditions, high efficiency and controllability, etc., also can select different functional monomers according to different application requirements, or adjust the pore-foaming agent system to prepare a series of organic-inorganic hybrid integral materials with different physical and chemical properties.

Description

technical field [0001] The invention relates to a rapid preparation of organic-inorganic hybrid porous monolithic materials based on photoinitiated mercapto-alkenyl polymerization, specifically mixing tetravinyl compounds, polymercapto compounds, porogenic solvents and photoinitiators uniformly and ultrasonically, and then using Photoinduced thiol-enepolymerization reaction (photoinducedthiol-enepolymerization reaction) prepares organic-inorganic hybrid porous monolithic materials with specific organic functional groups in one step. Background technique [0002] Monolithic materials with continuous porous structures have received increasing attention and have been widely used in fields such as catalysis, adsorption, separation media, and storage supports. In the field of separation and analysis, the capillary monolithic column is a monolithic material (mainly including organic monolithic materials, inorganic silica gel monolithic materials and organic-inorganic hybrid monoli...
