“…[3] For example, polysiloxanes with different groups have been reported to improve the intrinsic selectivity, which was usually accompanied by a general decrease in penetrant solubility and permeability. [4,5,6] Besides that, another powerful method is interfacial polymerization. This method can produce a composite membrane with thickness of interfacial polymerization selective layer of about 20 nm or more.…”

The thin film composite (TFC) membrane based on polypropylene (PP) and polyvinylidenefluoride (PVDF) was prepared using glutaraldehyde as the selective layer. The percentages of glutaraldehyde were optimized to maximize the permeability of carbon dioxide (CO 2 ) and selectivity as well. The TFC with 6% w/v of glutaraldehyde based on PVDF achieved the highest permeance of 881.70 GPU and 18.08 for selectivity through the increase in effective layer and skin layer thickness. This TFC promises to provide porous and hydrophobic membranes for use in membrane gas absorption (MGA) processes. The absorption of CO 2 in deionized water was studied in MGA system in which the mass transfer coefficient (K ) and CO 2 flux decreased with increasing CO 2 concentration in feed stream.
