Summary: Biofuels from biomass are being increasingly investigated as a response to the excessive consumption of petroleum-based fuels. The fermentation-separation coupled system, integrated with pervaporation (PV), has been developed to meet the high demands for biofuels. Polydimethylsiloxane (PDMS) based membranes are widely used and suggested to enhance the production and application of bioalcohols. However, there is a lack of comprehensive reviews on the latest progress of PDMS based membranes for biofuels pervaporation.

Summary: The study investigated the pervaporative desalination of synthetic seawater and brines using a PDMS thin-film composite membrane, demonstrating high water permeance and exceptional NaCl rejection. The PDMS composite membrane showed outstanding pure water flux even at high temperatures and with salt presence in the feed water, performing among the best compared with hydrophilic TFC polymer membranes reported previously.

Summary: A novel approach of fabricating PDMS@ZIF-8/PVDF hollow fiber composite membrane (HFCM) modules for ethanol-water separation was presented in this study. The as-prepared membrane exhibited an ultrathin separation layer achieved through precise regulation of the ZIF-8 membrane and defect repair by PDMS infusion. At the optimal packing density, the membrane showed remarkable ethanol flux with high PSI value and promising long-term stability for pervaporation.

Summary: In this study, PDMS/TEOS hybrid materials with different TEOS ratios were synthesized and ceramic tube-supported membranes were fabricated. The results showed that the ceramic tube-supported PDMS/TEOS membranes exhibited good hydrophobicity and excellent thermal stability, and achieved high performance in the separation of furfural-water mixture by pervaporation.

Summary: This study evaluates the effects of feed concentrations, temperature, and membrane microstructures on salt rejection of PDMS composite membrane for treating pharmaceutical wastewater. Various characterization techniques are used to analyze the microstructures of the membrane. The results show that increasing feed concentration of isobutanol decreases salt rejection, while increasing temperature increases salt rejection. The relaxation of PDMS polymer chains also affects the salt rejection.

Summary: This study aimed to improve the properties of Ultem(R) polyetherimide (PEI) by adding up to 2 wt% of the perovskite oxide La0.85Yb0.15AlO3 (LYA). The structure of the PEI/LYA films was characterized, and it was found that they exhibited a two-layer structure. The addition of LYA increased the separation selectivity in gas separation processes, and the PEI/LYA membranes showed effective pervaporation of a MeOH-CH mixture, with the highest separation index observed in the PEI/LYA(2%) membrane.

Summary: In this study, Co(OH)2 nanoparticles with a size smaller than 10 nm were prepared and incorporated into a mixed matrix membrane, resulting in improved separation performance. The well-distributed nanoparticles in the polymeric matrix could interact with benzene molecules, enhancing the separation performance for benzene. However, the performance of the membrane was weakened when the nanoparticles agglomerated.

Summary: In this study, a long alkyl chain-containing organosilica layer was utilized to modify silicalite-1 membranes, resulting in bi-layered BTESO/silicalite-1 composite membranes. After BTESO modification, the surface of the membranes became smoother, denser, and more hydrophobic. The modified membranes exhibited good separation performance in pervaporation, with increased ethanol flux and reduced water flux without sacrificing ethanol flux.
