The effect of incorporation of ZIF-67 nanoparticles on the polysulfone membranes in gas separation

Polysulfone (PSF) membranes were developed and modified by incorporating ZIF-67 nanoparticles. The effect of various percentages of ZIF67 was investigated by scanning electron microscopy, fourier transform infrared, X-ray diffraction. The permeation properties and performance of pure gases (N2, O2, CO2) was also evaluated. The ideal selectivity performance of composite membranes compared with the pure PSF membranes significantly increased in CO2/N2 and O2/N2 selectivity at pressure 1bar. It may due to, good interaction between the filler and the polymer and change in the polymer structure.
