Summary: Bis(triethoxysilyl)ethane (BTESE) nanoparticles were incorporated into aromatic polyamide (PA) membranes via in-situ polymerization to prepare BTESE nanocomposite PA (BTESE-TFN) membranes for reverse osmosis. The BTESE nanoparticles increased surface roughness, hydrophilicity, and changed the structure of the PA membranes, leading to improved salt rejection and water flux. Modification of organic bridged groups in the BTESE showed great potential to further enhance the water flux and durability of the BTESE-TFN membranes.

Summary: This study reported an innovative approach for controlling the polymerization process in the fabrication of thin film composite reverse osmosis membranes. The results showed that using a solvent mixture of toluene and n-hexane as the organic phase at a temperature of 20℃ significantly improved the salt rejection to 98.6% with a flux of 16.1 LMH. However, increasing the temperature further to 30℃ was not beneficial for membrane fabrication.

Summary: Thin film composite (TFC) membranes are widely used in reverse osmosis (RO)-based desalination processes due to their ideal separation performance. In this study, porous polyketone membranes prepared via non-solvent induced phase separation (NIPS) were explored as substrates for fabricating high-performance TFC membranes. Investigations on structure control and chemistry regulation showed that different polyketone substrates led to significant differences in thin layer formation during interfacial polymerization (IP), resulting in TFC membranes with varied permeance and performance.

Summary: Various robust, crystalline, and porous organic frameworks based on in situ-formed imine-linked oligomers were investigated. These oligomers self-assembled through collaborative intermolecular hydrogen bonding interactions via liquid-liquid interfacial reactions, and the resulting structures were unambiguously determined by single-crystal X-ray diffraction. The hierarchical arrangements increased the steric hindrance of the imine bond, preventing attacks from water molecules and improving stability.

Summary: This study investigates the anomalous water perm-selectivity of poly(vinyl butyral) (PVB) membrane in practical pervaporation (PV) process, and comprehensively analyzes its mechanism through experimental and theoretical methods. The results show that the surface reconstruction of PVB membrane in contact with ethanol exposes hydrophilic hydroxyl groups, improving its affinity to water. Swelling experiments further demonstrate the accumulation of water in the ethanol swollen membrane. Theoretical analysis confirms the mechanism of the anomalous phenomenon of PVB membrane.

Summary: A new sandwich-structured electrospun nanofibrous membrane (ENM) has been developed combining a fluffy layer and a hydrophobic layer to address the issue of pollution from airborne particulate matter (PM). By embedding micro-scale SiO2 particles into the nanofibers to construct a fluffy layer with large pores and spacing, and utilizing a hydrophobic PVDF nanofiber layer to prevent water fouling, the ENM exhibits stable permeability and competitive PM segregation efficiency. This unique structure may be beneficial for producing ENM-based mask filters with antifouling properties for personal protection.
