Abstract

The invention relates to a novel functionalized organic porous polymer and particularly relates to an ionic liquid functionalized ultra-crosslinking polymer and a preparation method thereof. The ionic liquid functionalized ultra-crosslinking polymer is prepared by reacting the following components in a molar ratio: 0.5-10% of a crosslinking agent, 10-70% of an imidazole ionic liquid and 10-80% of a monomer, wherein the used solvent is 1,2-dichloroethane; the monomer used in the ionic liquid functionalized ultra-crosslinking polymer is one or a combination of two or more of benzene, biphenyl, pyrrole, thiophene, furan, 1,3,5-triphenyl benzene or p-chloromethyl styrene, preferably, p-chloromethyl styrene. The porous polymer can be applicable to gas adsorption, especially capture and separation of CO2 gas.

Description

Technical field [0001] The present invention relates to a new type of functionalized organic porous polymer, in particular to an ionic liquid functionalized super-crosslinked polymer and a preparation method thereof. The porous polymer is suitable for gas adsorption, especially CO2 gas capture and separation . Background technique [0002] The large consumption of fossil fuels causes CO 2 Gas emissions have increased dramatically, and environmental and ecological changes have become increasingly serious. CO 2 Separation, capture, and storage of gas have received increasing attention. Traditional activated carbon has a short service life and is not easy to modify and regenerate; the framework of metal organic framework compounds is easy to collapse and the structure is unstable. At the same time, it is also sensitive to alkali, acid and water vapor and has poor chemical stability; preparation conditions for covalent organic framework polymers It is harsh and not easy to industri...
