Objective: Global warming is certainly an alarming environmental issue at present owing to rising CO2 level in the atmosphere that needs to be addressed instantly1. Carbon dioxide has been proven to be a greenhouse gas (GHG), which contributes to the increase in earth s surface temperature, ocean acidity and air toxicity, and may cause adverse climate changes. Existing scenario reveals the demand to reduce CO2 emissions by capturing it prior to emission, depositing in a suitable repository and then its utilization2. Technology already exists to capture CO2 encompassing chemical solvent absorption, physical adsorption, cryogenic fractionation, membrane separation, biological fixation as well as the O2 / CO2 combustion process3. The existing commercial CO2 capture facilities are based on the wet scrubbing process using aqueous alkanolamine solutions. It often suffers from issues with corrosion, amine degradation, and solvent losses. Therefore, there is a crucial need for new materials for efficient CO2 separation.
Ionic liquids (ILs), (low-temperature molten salts) are highly versatile materials that have been explored as nonvolatile and reversible CO2 absorbents for CO2 separation because of their high CO2 solubility4. Three intrinsic properties of ILs that differentiate them from common organic solvents and water are their negligible vapor pressures, thermal stability and tunable chemistry. The CO2 solubility and selectivity can be tuned by choice of cation, anion, and substituent s of the ionic liquids. The functionalization of polymers having ILs chemical groups led to the development of a new class of polyelectrolytes known as polymeric ionic liquids (PILs)
The aromatic polyamides, commonly referred as aramids, have been particularly useful as high-performance engineering materials because of their very high thermal stabilities and specific strengths, their high degrees of stiffness, and their low densities.
