Abstract：

Using 4,4-(9-fluorenylidene)-diamine and 1,?2,?4,?5-?benzene tetracarbonyl chloride as aqueous phase and oil phase reaction monomers respectively, hollow polyimide nanospheres were prepared by interfacial polymerization in the microemulsion system. Then, the mixture of PDMS, hollow polyimide nanospheres, and hexane was used as the coating solution, to prepare PDMS/hollow polyimide nanospheres/polyetherimide composite membranes by dip-coating method. The pure-gas permeances of oxygen and nitrogen and the ideal seperation factor of O2/N2 were investigated. The effects of the polymer concentration, the pre-crosslinking time, the immersion time, the pulling speed, and the curing temperature on the performance of composite membranes were investigated systematically. The results showed that the composite membrane had optimal permeance when the polymer concentration was 3 wt%, the pre-crosslinking time was 3 h, the immersion time was 120 s, the pulling speed was 0.5 m/min, and the curing temperature was 80 °C. At 0.2 MPa and 25 °C, the optimal permeance of O2 was 1676 accompanied with an ideal O2/N2 separation factor of 2.2.
