Abstract：

To improve CO2 separation performance of Pebax matrix membrane, TPP was used as the additive to blend with Pebax1657 matirx. The effect of TPP on the morphology, structure and gas permeation performance of Pebax/TPP blend was investigated. Pebax and TPP had a good compartibility which was characterized with SEM, XRD, ATR-FTIR and TGA analysis. With the incorporation of TPP, the solubility and diffusion coefficients of the blend membranes both increased. Thus, the CO2 and N2 permeability of Pebax/TPP membranes increased with the increase of TPP content, while the CO2/N2 selectivity reduced at the same time.
