摘 要：A series of poly（ethylene oxide）（PEO） membranes with star-like structures for CO2/H2 separation were prepared by the photo-polymerization method. The structure of PEO membrane was characterized by Fourier transform infrared spectroscopy（FTIR）. The thermal property and inter-segmental distance of polymer chain were investigated by differential scanning calorimetry and wide-angle X-ray diffraction, respectively. The density was determined by hydrostatic weighing method. The gas permeability, solubility and diffusivity of CO2 and H2 were investigated in the star-like PEO membranes. The relationship between gas permeation performances and physical properties was also discussed. The membrane exhibits outstanding CO2 permeability(about 9.7×10-11 cm3（STP） cm/cm2/s/Pa) and CO2/H2 selectivity（about 11） compared with other membranes.
