Abstract

The invention relates to a method for quickly preparing a porous integral material containing silicon based on a photoinduced thiol-yne polymerization reaction. The method specifically comprises the steps of mixing a di-alkynyl compound (functional monomer) containing silicon, a poly-sulfhydryl compound (functional monomer), a pore-forming agent and a photoinitiator, conducting ultrasonic dissolution on the materials, and then carrying out the photoinduced thiol-yne polymerization reaction under the illumination of an ultraviolet lamp with a certain wavelength to further prepare the hybridizedporous integral material. The preparing method has the advantages of being mild in condition, quick and the like; besides, different functional monomers can be selected or different pore-forming agent systems can be adjusted according to different application requirements, and a series of hybridized porous integral materials containing silicon with different physical and chemical features are prepared.

Description

technical field [0001] The invention relates to a rapid preparation of silicon-containing porous monolithic materials based on light-induced mercapto-alkyne polymerization. Specifically, after mixing silicon-containing diacetylenyl compounds, polymercapto compounds, porogenic solvents and photoinitiators uniformly and ultrasonically, using light Initiated thiol-alkyne polymerization reaction (photoinduced thiol-yne polymerization reaction) prepared silicon-containing porous monoliths in one step. Background technique [0002] In the past two decades, monolithic materials have received more and more attention, and have been widely used in the fields of catalysis, adsorption, separation media and storage carriers. Capillary monolithic column is a kind of monolithic material (mainly including organic monolithic material, inorganic silica gel monolithic material and organic-inorganic hybrid monolithic material) which is polymerized in situ inside the capillary to form a continuo...
