Summary: Surface segregation in blended polymer films has attracted significant interest, and a strategy to control this phenomenon in thin block-copolymer layers has been described in this study. By utilizing nonsolvent induced phase separation, solidified bilayer ultrafiltration membranes with self-assembled BCP top layers atop homopolymer substructures can be fabricated in a single casting step. Key factors for successful BCP surface segregation include careful selection of solvent systems and stabilization of micellar structures.

Summary: Membrane fouling is a serious issue in membrane technology that can be reduced by the technique of membrane modification through the addition of hydrophilic polymers or polyelectrolytes. This study systematically investigated the effect of different molecular weights of polyacrylic acid (PAA) on the structure and properties of polysulfone membranes. It was found that higher molecular weight PAA resulted in membranes with smaller pore size, higher hydrophilicity, and better antifouling performance. The addition of PAA also led to a decrease in water contact angle and an increase in rejection for humic acid solutions.

Summary: Asymmetric block copolymer ultrafiltration membranes find wide applications in water purification, virus filtration, and drug delivery. However, numerical flow characterization of these membranes has been challenging due to difficulties in hierarchical pore structure delineation and lack of efficient image-based modeling approach. In this study, we used 2D scanning electron microscopy (SEM) images with different resolutions to delineate the hierarchical asymmetric pore structure. We proposed a novel stochastic pore network model to simulate flow, and computed the absolute permeabilities of two asymmetric block copolymer ultrafiltration membranes, which showed good agreement with experimental results.

Summary: This study investigates the swelling behaviors of thin films of polystyrene-block-poly(dimethylsiloxane)-block-polystyrene (PS-b-PDMS-b-PS) in linear alkanes and produces well-defined nanoporosities in the films through selective swelling-induced pore generation. The pore sizes and porosities are determined by the interaction between the alkanes and the constituent blocks. The results demonstrate that n-hexane can produce a porosity >30% at room temperature within a duration as short as 1 min. The porous films exhibit interconnected and accessible porosities, tunable flux, and excellent pressure resistance, indicating their potential applications in organic solvent filtration and oil/water separation.

Summary: This study reports the engineering of thin microporous membranes using microporous organic nanotubes (MONs) derived from covalent organic frameworks through interfacial polymerization. By incorporating a highly porous and interpenetrated MON layer on the membrane, polyamide membranes with Turing structure, enhanced microporosity, and reduced thickness were formed. The modified MON membranes exhibited remarkable water permeability and high retention of boron and phosphorus under alkaline conditions. Molecular simulations showed that the introduction of MONs reduced amine molecule diffusion and increased membrane porosity and water molecule density around the membrane pores. This study provides new insights into creating high-permeability membranes for precise nanofiltration.

Summary: This study explores an additive manufacturing strategy using spray-coating to prepare large-area polyamide composite membranes with tunable thickness. By utilizing spray-coating, composite membranes consisting of polyamide layers and carbon nanotube layers are additively constructed on porous substrates. The polyamide thickness can be independently adjusted by changing monomer concentrations, and water permeance is found to be related to the thickness. A large-area membrane with high water permeance and rejection rate is successfully prepared under optimal conditions. This study suggests that additive manufacturing is shifting the traditional paradigm in the preparation of high-performance separation membranes.

Summary: This study demonstrates a strategy of solvent vapor annealing to reorient the pore channels of covalent organic frameworks (COFs) from anisotropic orientation to perpendicular alignment. The COF thin films with flexible N-H bonds enable molecular rearrangement. A solvent with low relative permittivity and a conjugated structure is used to easily penetrate the COF interlayers. The solvent vapor weakens the pi-pi interaction and allows the COF monolayers to dissociate, leading to the reorientation of COF pore channels and improved separation precision.
