中文摘要：

合成的膜为 CO2 分离由于他们的潜在的应用吸引了增加的注意。在这个工作，陶器的支持的 polydimethylsiloxane (PDMS ) 并且 poly (乙烯乙二醇) diacrylate (PEGDA ) 合成的膜被准备。微观结构和 compositemembranes 的物理化学的性质被描绘。准备条件系统地被优化。同样准备的膜的煤气的分离性能被纯气体和 CO2， N2 和 H2 的二进制煤气的浸透测量学习。实验证明作为硅酮橡胶， PDMS 展出了更大的渗入和更低的分离因素。相反地， PEGDA 合成的膜介绍了更小的煤气的渗入但是为 CO2/N2 的更高理想的选择。用聚合支持或独立的膜比作那些膜的表演，二种有点合成的膜展出了更高煤气的渗入和可接受的选择。因此，陶器的支持的合成的膜能从轻气体作为 CO2 分离的一个候选人被期望。

英文摘要：

Composite membranes have attracted increasing attentions owing to their potential applications for CO2 separation. In this work, ceramic supported polydimethylsiloxane （PDMS） and poly （ethylene glycol） diacrylate （PEGDA） composite membranes were prepared. The microstructure and physicochemical properties of the compos- ite membranes were characterized. Preparation conditions were systematically optimized. The gas separation performance of the as-prepared membranes was studied by pure gas and binary gas permeation measurement of CO〉 N2 and H〉 Experiments showed that PDMS, as silicone rubber, exhibited larger permeance and lower separation factors. Conversely, PEGDA composite membrane presented smaller gas permeance but higher ideal selectivity for CO2/N2. Compared to the performance of those membranes using polymeric supports or freestanding membranes, the two kinds of ceramic supported composite membranes exhibited higher gas permeance and acceptable selectivity. Therefore, the ceramic supported composite membrane can be expected as a candidate for CO2 separation from light gases.
