Summary: This study reveals a previously unexplored adhesion mechanism in mussel-inspired chemistry, where 5,6-dihydroxyindole (DHI) moieties play a crucial role, challenging the conventional belief of catechol-dominated adhesion. The high adhesion strength of polydopamine (PDA) is attributed to the abundant yield of DHI moieties achieved through oxidation and cyclization during self-polymerization, suggesting that substituent chemistry and self-polymerization can govern adhesion in mussel-inspired materials.

Summary: This study reports Janus membranes with asymmetric cellular adhesion behaviors for regenerating the eardrum. The membranes are constructed by co-depositing a tannic acid (TA)/3-aminopropyltriethoxysilane (APTES) coating on one surface of the polypropylene microfiltration membrane. Cellular experiments indicate good biocompatibility and asymmetric cellular adhesion properties of the Janus membranes. The repair of the tympanic membrane perforation experiment and LDV measurements prove that the hydrophilic surface of the membranes repairs perforated eardrums while the hydrophobic surface reduces hearing loss by avoiding adherence to the inner ear tissue.

Summary: We report a sequential process of blade coating-spraying-interfacial polymerization for scalable preparation of high-performance desalination polyamide nanofilms. Our strategy highly reduces the utilization of organic solvents to meet the demands of lower carbon footprint.

Summary: Interfacial polymerization is a widely used method for synthesizing high-performance materials, but monitoring the growth of polymers during this process has been challenging. To overcome this, we have utilized the aggregation-induced emission effect to observe the entire interfacial polymerization process in real time. Using a confocal laser scanning microscope, we obtained clear images of the polymer and characterized its structural heterogeneity. Interestingly, our study revealed that the polymer density is higher away from the interface, contrary to expectations of homogeneity. The changing ratio of monomers in the reaction region explains this density gradient. Additionally, we demonstrated the precise growth kinetics of the polymer under different conditions. Our results provide a novel platform for understanding the mechanisms and properties of interfacial polymerization.

Summary: In this work, fluorinated polymers with perfluoroalkyl groups and hydrophilic oligo(ethylene glycol) units were designed and synthesized. The elongation of hydrophilic segments and functionalization with perfluoroalkyl end groups decreased the interfacial tension and ability of the polymers to precipitate at the interface. This study suggests that low interfacial tension and strong capability of interfacial precipitation are beneficial to droplet stabilization and honeycomb pattern formation.

Summary: This review summarizes recent advances in tailoring interfacial polymerization using interfaces beyond the conventional alkane-water interface to achieve high-performance separation films with designed structures. Diverse liquid-liquid interfaces are introduced for synthesizing separation films by adding co-solvents into the organic phase and/or the aqueous phase, respectively, or by replacing one of the liquid phases with other solvents. Innovative liquid-gel and liquid-gas interfaces are then summarized for the synthesis of polymer thin films for separation. Novel strategies to form reaction interfaces, such as spray-coating, are also presented and discussed. In addition, the review discusses the details of how a physically or chemically patterned substrate affects interfacial polymerization. Finally, the potential of unconventional interfaces in interfacial polymerization is forecast with both challenges and opportunities.

However, it is difficult to incorporate these techniques with spiral wound modules (SWMs) widely used in water and wastewater treatment. This study developed a prototype membrane system to accommodate angular vibrations with a modified SWM, and experimental results showed that applying angular vibrations can effectively control algal fouling in an SWM with lower energy consumption compared to traditional methods.
