Summary: This study proposes a strategy to directly fuse the functional attributes of small additives into supramolecular polyelectrolyte nanoporous membranes under ambient conditions. The pore size distributions and mechanical properties of the membranes are controlled by tuning the hydrogen bonding interactions between the additives and the polyelectrolyte. The study demonstrates that small dye additives/homo-poly(ionic liquid) solutions can be used as versatile inks to create colorful light emitting films with robust underwater adhesion strength, excellent stretchability, and flexibility on various surfaces.

Summary: The importance of enhancing the design of percolating nanopore structures in block copolymers (BCPs) has been widely demonstrated in various cases over the past several decades. However, it remains challenging to prepare the desired porous structures in a rapid, facile, and universal way. In this study, an unconventional strategy has been developed to rapidly generate nanoporous polystyrene-based BCPs with arbitrary structural characteristics, regardless of the BCP bulk morphology. This universal pore-forming strategy allows for the formation of advanced membranes with sustainable CO2-based BCPs, efficiently rejecting 94.2% brilliant blue R (826 g mol(-1)) after only 1 second of soaking. Meanwhile, the water permeance remains around 1020 L (m(2) h bar)(-1), which is 1-3 orders of magnitude higher than that of other membranes. This strategy provides an excellent opportunity to introduce percolating pore structures in newly developed BCPs that may not be addressed by previously reported pore-forming methods.

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: The research demonstrates that the nature of the substrate has a significant impact on the self-assembled morphology and surface patterns of bottlebrush block copolymers with different side-chain lengths in films, despite the typical tendency of these polymers to form lamellar structures. By manipulating the substrate chemistry, unique morphologies can be induced in bottlebrush block copolymer films.

Summary: We have developed a multiscale simulation model for predicting solute diffusion through porous triblock copolymer membranes. The model combines self-consistent field theory (SCFT) and on-lattice kinetic Monte Carlo (kMC) simulations. Solvation is simulated in SCFT by constraining the glassy membrane matrix while relaxing the brush-like membrane pore coating against the solvent. The kMC simulations capture the resulting solute spatial distribution and concentration-dependent local diffusivity in the polymer-coated pores.

Summary: In this hi-tech world, smart coatings have attracted significant attention from materials scientists due to their versatile applications. The layer-by-layer (LbL) technique is commonly used to produce suitable smart coatings. In this study, a smart coating with healing, antifogging, and fluorescence properties was fabricated using the LbL assembly of an anionic amphiphilic block copolymer latex and cationic inorganic POSS nanoparticles. This finding provides a simple water-based LbL coating with low VOC and multifunctional properties, which can be potential material for various applications.

Summary: This study presents a general strategy to continuously tune the emission color of a single-fluorophore aggregate by polymerization-mediated through-space charge transfer (TSCT). The color tunability originates from the structurally dependent TSCT process, which can be fine-tuned by varying molecular parameters to adjust the solid-state emission color.

Summary: The calculation of relative energy difference is important in various practical applications. This study analyzed the performance of Graph Neural Networks (GNNs) in predicting energy differences and found that GNNs exhibit a correlated error that can be reduced through subtraction, leading to more precise predictions. The results show that GNNs can achieve comparable error reduction to Density Functional Theory (DFT) and can distinguish subtle energy differences. The similarity in local embeddings is related to the magnitude of error cancellation, highlighting the need for proper training methods.
