| 摘 要： | 两步法制备了4A沸石填充的端羟基聚丁二烯基聚氨酯膜HTPB-PU/4A,并研究了CO2、H2、O2、N2的气体透过性能.结果表明:沸石与膜的相容性较好,添加4A沸石后,膜的热稳定性明显提高,O2渗透性及O2/N2选择性显著改善；随沸石添加时间的增加,膜对各种气体体系的选择性先增加后减小,而渗透性则先增加后趋于稳定；随硬...

| Abstract: | Zeolite 4A-filled hydroxyl terminated polybutadiene(HTPB)-based polyurethaneurea(PU) membranes,HTPB-PU/4A,are prepared by a two-step polymerization process to investigate the permeability of CO2,H2,O2 and N2.The results show that zeolite 4A particles are compatible with the PU segments and the incorporation of the zeolite 4A particles can apparently improve the thermal stability,permeability of O2 and selectivity of O2/N2 of the membranes.With the adding time of zeolite 4A increasing,the selectivity of the ... |
