本工作通过将薄膜浇铸在二氧化硅浸渍的陶瓷基板上，研究了二氧化硅颗粒对 6FDA-IPDA 薄膜气体传输性能的影响。 AnoporeTM陶瓷载体的孔结构为二氧化硅颗粒与聚合物链的紧密接触提供了理想的环境。总体而言，与 6FDA-IPDA 均质膜的性能相比，所得的氧氮分离膜的性能得到显着改善。
The effect of silicon dioxide particles on the gas transport properties of 6FDA-IPDA thin films was investigated in this work by casting the films on silica impregnated ceramic substrates. The pore structure of the AnoporeTMceramic support provided an ideal environment for bringing the silica particles into intimate contact with the polymer chains. Overall the properties of the resulting membranes for separation of oxygen from nitrogen are significantly improved compared to the properties of a homogeneous film of 6FDA-IPDA.
