This may be because of powerless cooperation between PSf network and zeolite RHO, the impact of which was more noteworthy at higher zeolite stacking levels. Consolidation of low stacking of 1 wt% zeolite RHO into PSf didn’t clearly influence the membrane morphology. The free volume between polymer chain and zeolite RHO expanded, causing a broken interface with the presence of non-particular interfacial voids at the PSf/zeolite RHO interfacial district . These interfacial voids are non-specific as it permits gas atoms to go through the voids with less opposition as opposed to going through zeolite pores . Henceforth, the CO2 penetrability expanded however the ideal CO2/CH4 selectivity was forfeited when zeolite RHO stacking in the MMMs expanded from 1 to 5 wt%. Figure 12 shows the gas pervasion and division execution of flawless PSf membrane and RHO/PSf MMMs.
