摘要

Polymerized ionic liquids (PILs) were successfully prepared by using 4-(vinylbenzyltrimethyl)ammonium, [VBTMA] as the cation and alanine as the anion. The monomer [VBTMA]Ala was reacted with AIBN as radical initiator to produce poly[VBTMA]Ala. The polymer was characterized by using NMR and FTIR. Thermal degradation behavior for Poly[VBTMA]Ala was 168.70 °C and glass transition temperature (T_g) was not detected even at second cycle. The surface area, pore size and pore volume were determined by using BET surface area and pore size analyzer which showed that Poly[VBTMA]Ala has mesoporous structure. The morphology was determined by FESEM. The CO_2 adsorption was measured by gas adsorption cell which showed that the mole of CO_2 adsorb increased as pressure increased.
