Summary: This study examines the effects of CO2 partial pressure and temperature on the CO2 absorption and transport properties of amino acid salts (AASs) in polymeric facilitated transport membranes (FTMs). It is found that PZEA-Sar has a higher CO2 loading and a more efficient transport pathway compared to PZ-Gly and PZEA-Gly. The formation of reaction products is influenced by the adjustment of CO2 partial pressure and temperature. The enhanced CO2 permeance of FTMs can be attributed to the accelerated diffusion of reaction products.
