Two types of DESs were synthesized by mixing and subsequently heating PC with glycerol or ethylene glycol separately. The mechanism of interaction was inferred from the spectral analysis (FTIR) whereas thermal study (TGA) was performed to analyze the stability of the membrane. Experiments were carried out to analyze the permeability and separation factor of the membranes. The PC-Glycerol based SLM reported permeability of 34 Barrer and ideal selectivity of 59 while PC-Ethylene Glycol based SLM showed permeability of 20 Barrer and separation factor of 34 under similar operating conditions. Systematic analysis was made for some of the important operating parameters affecting the separation efficacy such as feed composition and temperature. The acquired results were  compared with the currents state-of-the-art by plotting on the well-known Robeson’s upper bound plot. The current  efforts of exploitation of PC-DES membrane will lead to new prospective for effective mitigation of CO2 from the gas  mixture.
