Abstract

Global warming caused as opposed to greenhouse gases, such as carbon dioxide, has become a pressing concern around the world. To help reduce the emission of carbon dioxide, ILs, like ([1-ethyl-3-methylim/idazolium] [bis(trifluoromethylsulfonyl)imide]), have been proposed as point source GHG capture solvents. In this work, the ionic liquid is polymerized with polyethylene glycol diacrylate. Linear spectrum was measured to check the absorbance of the CO2 in the sample, and 2-Dimensional Infrared (2D-IR) Spectroscopy was used to measure the frequency-frequency correlation function of the system. Preferential solvation is the model that will be established for our system as an alternative to the core-shell-matrix model.
