The polarized silver nanoparticles (AgNPs) were used as carriers in CO₂ separation through facilitated transport. AgNPs were polarized and stabilized by adding p-benzoquinone (p-BQ). This polymeric composite membrane was used for CO₂/N₂ separation, and showed high-selective performance. Through CO₂ and N₂ gas permeation experiment, it was confirmed that these membranes showed ideal selectivity of 117 or more. These separation performances were significantly improved compared to pristine PVP and were due to the selective and reversible interaction between polar CO₂ molecules and AgNPs polarized by p-BQ. Positive charged density on surface of particles was analyzed by XPS and it was found that it could accelerate the transport of CO₂ molecules through dipole-dipole interaction.
