Problems solved by technology

However, this silicon-based hybrid monolithic material needs to be prepared through multiple steps, and the process is still relatively cumbersome and sensitive to pH. In particular, the rate of free radical polymerization used is difficult to control, which leads to repeatability in the preparation. There are still big deficiencies in

Abstract

The invention relates to the field of macromolecule, specifically to an organic porous integral material and a preparation method and application thereof. Acrylic ester containing unsaturated double bond, a functional monomer containing mercapto group and an initiator are mixed; a photoinitiator is added; the mixed solution undergoes ultrasonic dissolution in a pore forming agent; a free-radical polymerization reaction is carried out under UV-irradiation to in situ form a porous organic integral material, namely an organic porous integral material with different surface properties and functions. The organic porous integral material has a structured microstructure and ordered porous channels and has good application in chromatographic separation. The preparation method has advantages of simple and fast operation, fast reaction speed and the like. In addition, different organic functional monomers and pore forming agent systems can be selected according to different application requirements, and a series of porous organic integral materials with different physical and chemical properties are prepared.

Description

technical field [0001] The present invention relates to a kind of photoinitiated mercapto-acrylic ester polymerization reaction to prepare organic porous monolithic material and its preparation method and application, specifically dipentaerythritol penta- / hexa-acrylic acid (dipentaerythritol penta- / hexa-acrylic acid) containing unsaturated double bonds -acrylate, DPEPA), mercapto compounds and photoinitiators are ultrasonically dissolved in porogenic solvents, and then undergo radical polymerization under ultraviolet light irradiation to form porous organic monolithic materials in situ, by adjusting the concentration of monomers and porogens The proportion of organic porous monoliths with different surface properties and functions can be prepared. Background technique [0002] Porous monolithic material is a new type of porous micro-separation medium that has received extensive attention in recent years. Compared with traditional packed column separation materials, it has th...
