Mixed‐matrix membranes were prepared by incorporating functionalized silica nanoparticles (SNPs) into the poly(ether‐block‐amide). The gas permeation properties of membranes were investigated for the separation of N2 and CO2 from CH4. Results revealed that chemical modification of SNPs and incorporation of the carboxylic groups on its surface had a strong interaction with the polymer matrix and improved the distribution of the nanofiller in the membrane matrix. According to the gas permeation experiments at various SNPs loadings and feed pressures, different trends were observed for the permeability and selectivity. Incorporation of the modified‐SNPs nanofiller into the membrane enhanced the CH4 permeability, as well as the CH4/N2 and CO2/N2 selectivities.

用于天然气净化的含功能化二氧化硅的CH4选择性混合基质膜
通过将功能化的二氧化硅纳米颗粒（SNP）掺入聚（醚嵌段酰胺）中来制备混合基质膜。研究了从CH 4中分离N 2和CO 2的膜的气体渗透性能。结果表明，SNPs的化学修饰和羧基在其表面的结合与聚合物基体具有强相互作用，并改善了纳米填料在膜基体中的分布。根据在各种SNP负载和进料压力下的气体渗透实验，观察到渗透率和选择性的不同趋势。将修饰的SNPs纳米填料掺入膜中可增强CH 4的渗透性以及CH4 / N 2和CO 2 / N 2选择性。
