In this study, CO_2 interactions with 1,3-dimethylimidazolium dimethylphosphate([MMIM]DMP),1-ethyl-3-methylimidazolium dimethylphosphate([EMIM]DMP) and 1-ethyl-3-methylimidazolium diethylphosphate([EMIM]DEP) that contain inorganic ester groups based on phosphate, were investigated using ATR FT-IR spectroscopy. CO_2-induced swelling, CO_2 diffusivity and CO_2 capture capacity were simultaneously measured to identify CO_2 capture mechanisms, kinetics and diffusion behaviors as a function of the alkyl chain length of the cation. Henry's law constants of CO_2 were found to be in the range of 4-11 MPa, which is in agreement with those reported in other studies.展开更多
