【摘要】 分别用甲基硅橡胶（MSR）,聚（4-甲基戊烯-1）（TPX）及其共混物,通过溶液涂布法,在多孔聚丙烯底膜（Duragard 2400）之上制成富氧超薄膜。比较了得到的复合膜的富氧性能。MSR与TPX共混物制成的复合膜性能明显优于MSR及TPX单独及二者重叠涂膜的结果,当共混物组成MSR/TPX=1.3/1.0时,得到了最好的结果:JO2=1×1.8×10^-4,αO/N=2.0更多还原

【Abstract】 The ultrathin oxygen enrichment membranes were prepared by solution cast method onto porous PP support （Durard 2400） with methyl silicone rubber （MSR） , poly （4-methylpentene-1） （TPX） and their mixture. The performance of oxygen enrichment of the composite membranes were compared.The results of blend MSR and TPX was better than that of MSR orTPX alone or their combination. The best result Jo₂= 1 -1.8×10^-4, αo/n=2.0 was obtained at MSR/TPX= 1.3./1.0.更多还原
