A new poly(ionic liquid) of N,N-methylenebisacrylamide (MBA)-crosslinked-poly(4-vinylbenzyltriethylammonium hexafluorophosphate)(MBA-crosslinked-P[VBTEA][PF6]) is prepared through the ion exchange of KPF6 with the precursor of MBA-crosslinked-P[VBTEA][Cl]; the precursor is synthesized by 4-vinylbenzyltriethylammonium chloride and MBA via inverse suspension polymerization. MBA-crosslinked-P[VBTEA][PF6] is a thermally stable (decomposes at nearly 300 degrees C) and porous (apparent porosity of 64.3% and specific surface of 39.12 m(2)/g) polymer particle with high purity, as indicated by Fourier transformed infrared, energy dispersive spectroscopy, thermogravimetric, scanning electron microscopy, and porous analyses. It is observed that MBA-crosslinked-P[VBTEA][PF6] has good CO2 adsorption capability of 14.04 mg/g at 0.2 MPa and 25 degrees C, and can be recovered by desorption at vacuum and 80 degrees C, and reused with 99% CO2 adsorption after four cycles.
