Summary: Antibiotic abuse has become a burden on patients and healthcare systems, leading to a need for non-antibiotic wound dressings. However, hydrogel wound dressings with good recoverability, toughness, and excellent antibacterial properties still face obstacles. In this study, a series of semi-interpenetrating network (semi-IPN) hydrogels were developed using quaternized chitosan (QCS) and polyacrylamide (PAM) through a one-pot method, which showed exceptional mechanical performance and remarkable antibacterial activity. The integration of quercetin (QT) further enhanced the antibacterial properties against S. aureus and E. coli. These high-elastic hydrogels have potential applications in wound dressing, tissue repair, chronic wound care, and other biomedical fields.

Summary: Hydrogels have gained significant attention in oil-water separation due to their high hydrophilicity and low viscosity. However, their mechanical properties often limit their applications. In this study, a polyvinyl alcohol/chitosan/polyacrylamide interpenetrating polymer network hydrogel (HAPC-Gel) was created, which exhibited excellent mechanical properties. The HAPC-Gel coating filter cloth showed underwater super-oleophobicity and could effectively separate oil-water mixtures in various oil phases and complex environments. The results demonstrate the promising applications of HAPC-Gel composites in oil-water separation.

Summary: This article discusses the synthesis of pseudo-semi interpenetrating polymer networks (pseudo-semi IPNs) and their potential in engineering applications. Pseudo-semi IPNs were synthesized by sequentially polymerizing thermoplastic polymers (TPEs) in the presence of thermosetting elastomer (TSEs). The elastic modulus, effective crosslinking density, and physical crosslinking density of TSEs and pseudo-semi IPNs were investigated, and the inherent interactions and entanglements of pseudo-semi IPNs were discussed. The results show that the addition of TPEs to the TSE matrix significantly improves the ductility and strength of the material matrix.
