Poly(amidoamine) (PAMAM) dendrimer is entrapped in a poly(ethylene glycol) network by photo-polymerization of PEG dimethacrylate (PEGDMA)..in the presence of the dendrimer. The resulting polymeric membrane displays excellent CO 2 separation properties over H2. The dendrimer content, generation of the dendrimer, and relative humidity are crucial factors to characterize CO2 separation performance of the dendrimer containing polymeric membrane. Especially, the UV curing of immiscible pair of the dendrimer and PEG results in the formation of a bicontinuous structure upon macrophase separation in a coupe of microns scale. The phase-separated structure also determines preferential CO2 permeation.
