N2 - Poly(amidoamine) (PAMAM) dendrimers showed high CO2 separation properties and were successfully immobilized in a poly(ethylene glycol) (PEG) network upon photopolymerization of PEG dimethacrylate. The PAMAM dendrimer incorporation ratio was readily controlled, and a stable self-standing membrane containing up to 75 wt.% PAMAM dendrimer was obtained. The CO2 separation properties over smaller H2 were investigated by changing the PAMAM dendrimer content or generation and CO2 partial pressure (Δ PC O2) under atmospheric conditions. Especially, a polymeric membrane containing 50 wt.% PAMAM dendrimer (0th generation) exhibited an excellent CO2/H2 selectivity of 500 with CO2 permeability of 2.74 × 10-14 m3(STP)m/(m2 s Pa) or 3.65 × 103 barrer (1 barrer = 7.5 × 10-18 m3(STP)m/(m2 s Pa)) when a mixture gas (CO2/H2: 5/95 by vol.) was fed at 25 °C and 100 kPa with 80% relative humidity. This polymeric materials are promising for a novel CO2 separation membrane.
