Porous materials have always attracted high scientific interest because of their outstanding performance and potential applications in various fields, including adsorption and gas separation. Hyper-crosslinked polymers (HCLPs) have several advantages over other porous materials, they show extremely high surface areas and porosity, low density, outstanding adsorption properties, high chemical, and thermal stability.
Herein, we reported a synthesis, characterization, and the CO2 (and other gases) adsorption performance of series of novel styrene-divinylbenzene based HCPs. The material was prepared in two steps. The first step involved the radical copolymerization of divinylbenzene (DVB) and 4-vinylbenzyl chloride (VBC), under solvothermal condition to generate porous polymers with high surface area above 700 m2 g−1. In the second step, various polyamine species were applied to react with the alkyl chloride groups and functionalize the pore surface
to improve the CO2/N2, CO2/CH4 and CO2/H2 selectivity.
