摘要：

Ionic liquid modified poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) was synthesized by introducing imidazolium-based, pyridinium-based, and ammonium-basd ionic liquid groups to the methyl position of PPO. Membranes were prepared from the different types of ionic liquid modified PPO (IPPO), and the permeability of CO2 and N-2 in these membranes was characterized. For having the CO2-philic ionic liquid groups in the structure, the CO2 solubility of the IPPO is better than that of PPO, while the CO2 diffusivity in the IPPO is proportional to glass transition temperatures. The adsorption and desorption of CO2 in the IPPO were also investigated, and the results manifest that the adsorption and desorption of CO2 in IPPO are completely reversible, which makes the polymer promising as solid adsorbent materials for CO2 separation.
