Summary: In this study, pervaporative mixed matrix membranes (MMMs) composed of newly synthesized porous UiO-66 filler and poly (vinyl alcohol) (PVA) were investigated for dewatering n-butanol (BuOH) from BuOH/H2O and BuOH/ethanol/H2O solutions. The effects of filler loading, feed concentration, and feed temperature on membrane dehydration performance were studied in terms of pervaporation flux/separation factor, pervaporation separation index, and component permeance/selectivity. The results showed that increasing the feed water concentration or temperature led to an increase in total permeation flux but a decrease in dehydration separation factor. The UiO-66/PVA MMMs exhibited great potential for practical BuOH dehydration applications.

Summary: The study investigated the optimal polymeric blending ratio between cellulose acetate (CA) and polyvinylidene fluoride (PVDF) to create a blended polymeric membrane with enhanced properties. The inclusion of nano-sized metal organic framework (UiO-66 MOF) further improved the membrane performance. The resulting hybrid membrane showed promising salt rejection and permeate water flux for water desalination applications.

Summary: The use of mixed matrix membranes (MMMs) comprising metal-organic frameworks (MOFs) has been recognized as an effective strategy for enhancing gas separation efficiency. However, the poor compatibility between the filler and matrix may compromise the separation performance. This study modifies the filler to improve its compatibility with the matrix and enhance the selectivity of CO2 over N-2 and CH4.

Summary: In this study, MMMs were prepared using PIM-1 as the polymer matrix and UiO-66-AO as the filler. The hydrogen bond network formed between the functional groups on the filler and the polymer matrix improved compatibility. The selective adsorption of CO2 by the filler promoted CO2 transport and enhanced gas selectivity. UiO-66-AO@PIM-1 MMMs exhibited excellent performance and have great potential for CO2 separation.

Summary: Novel mixed matrix membranes (MMMs) were fabricated by incorporating bimetallic Zn/Co-ZIF nanoparticles into the prototypical polymer of intrinsic microporosity (PIM-1). The addition of Zn/Co-ZIF nanoparticles enhanced the hydrophobicity of the MMMs and improved the separation performance of ethanol/water and butanol/water mixtures. It was found that Zn/Co-ZIF/PIM-20 wt% membrane showed the highest separation and flux among all the membranes tested.
