Abstract

Porous poly(ionic liquid)s based on copolymer of 1-allyl-3-methyimidazolium hexafluophosphate and acrylonitrile with 70:30 monomer ratio (PAMIH-AN) and Poly(Vinylbenzyl trimethylammonium tetrafluoroborate) (P[VBTMA][BF₄]) were prepared and characterized for CO₂ sorption. The effects of different pore-forming agents on the porous structure and CO₂ sorption were discussed respectively. The CO₂ sorption capacity of porous P[VBTMA][BF₄] is apparently higher than that of PAMIH-AN. For example, porous P[VBTMA][BF₄] treated with n-heptane as the pore-forming agent has the highest CO₂ sorption capacity of 1.15 wt %, while the corresponding pore-forming agent of PAMIH-AN is toluene with 0.22 wt % at 273 K and 0.101 MPa.
