“…So when the SPSF has a sulfonation degree of 30%, the cross-section of M2 shows a combination of finger holes and sponge holes; when the SPSF has a sulfonation degree of 50%, smooth finger-like holes appear in the cross section of M3. 28,29 …”

“…This is mainly because (1) the stronger hydrogen bonding of the sulfonic acid groups destroys the original crosslinking between the polymer molecules in the casting solution and (2) the sulfonic acid groups will cause the expansion of the polymer volume and increase the speed of the chain, which decreases the mechanical strength of the membrane. 28 In order to evaluate the thermodynamic stability of the PES/ SPSF blend system during the phase separation process, the cloud point (CP) of the casting solution blend system was measured, and the results are shown in Table 8. When SPSF is added, the amount of water required for the casting liquid to reach the cloud point also increases.…”

“…Carbon nanotubes (CNTs) in MMMs show a robust and promising possibility of overcoming the trade-off of selectivity and permeability, which is the primary issue experienced in MMMs [ 113 , 114 , 115 , 116 ]. CNTs also have a higher rapid gas transport rate that allows for higher permeability compared with the other fillers mentioned [ 117 , 118 ].…”

With an ever-increasing global population, the combustion of fossil fuels has risen immensely to meet the demand for electricity, resulting in significant increase in carbon dioxide (CO2) emissions. In recent years, CO2 separation technology, such as membrane technology, has become highly desirable. Fabricated mixed matrix membranes (MMMs) have the most desirable gas separation performances, as these membranes have the ability to overcome the trade-off limitations. In this paper, blended MMMs are reviewed along with two polymers, namely polyether sulfone (PES) and polyethylene glycol (PEG). Both polymers can efficiently separate CO2 because of their chemical properties. In addition, blended N-methyl-2-pyrrolidone (NMP) and dimethylformamide (DMF) solvents were also reviewed to understand the impact of blended MMMs’ morphology on separation of CO2. However, the fabricated MMMs had challenges, such as filler agglomeration and void formation. To combat this, functionalised multi-walled carbon nanotube (MWCNTs-F) fillers were utilised to aid gas separation performance and polymer compatibility issues. Additionally, a summary of the different fabrication techniques was identified to further optimise the fabrication methodology. Thus, a blended MMM fabricated using PES, PEG, NMP, DMF and MWCNTs-F is believed to improve CO2/nitrogen separation.

“…Tavangar et al. 21 investigated the performance of highly sulfonated polyethersulfone/polyethersulfone membranes for oil/water separation. They found that the membrane consisting of 50 % sulfonated polyethersulfone and 50 % polyethersulfone with a sulfonation degree of 37 % has the highest permeability, with 93.3 % oil rejection.…”

The microfiltration membrane separation process in oil effluent treatment was investigated experimentally. The flux of poly(styrene‐co‐acrylonitrile) with 25 wt % (SAN25) and 30 wt % (SAN30) of acrylonitrile fraction using different solvents in two different feed types (distilled water and 5000 mg L−1 stabilized oil‐in‐water (O/W) emulsion) was studied. In the case of the O/W emulsion, the performance of the membranes was evaluated using oil rejection. The chemical oxygen demand test was used to analyze the oil concentration in the permeate and to calculate the rejection. The results show a decline in the O/W treatment flux in comparison with the distilled water. The water permeate of SAN25 using dimethylformamide and N‐methyl‐2‐pyrrolidone was 200 and 170 L m−2h−1, respectively, and permeate flux values of 290 and 210 L m−2h−1 were obtained using SAN30.
