Summary: The poly(N-vinyl imidazole) cross-linked beta-cyclodextrin hydrogel assembled through microwave-assisted free radical polymerization demonstrates superior blood clotting kinetics and biocompatibility, showing potential as a carrier for sustained release of drugs. Its rapid hemostatic behavior, cytocompatibility, hemocompatibility, and controlled drug release characteristics make it an excellent alternative for severe hemorrhagic conditions.

Summary: Researchers have developed various super wetting materials by modulating the properties of hyper cross-linked poly(ionic liquid)s (HCPILs) through Friedel-Crafts alkylation and ion exchange. These materials can efficiently separate oil-water mixtures, especially emulsions, in complex environments. They exhibit excellent durability and stability in harsh conditions, such as high concentrations of salt, acid, and basic solutions.

Summary: In this study, anisotropic hydrogels with rich structural hierarchy and tunable mechanical properties were fabricated using a simple strategy involving the minor polymer as the performance and network regulators. The presence of PVP as a minor component promoted the formation of bridging fibers in the anisotropic hydrogels, resulting in superior mechanical strengths compared to isotropic hydrogels or single-component anisotropic ones. The dendritic structure also improved the strength perpendicular to the aligned direction, leading to more balanced mechanical performance in the PVA/PVP anisotropic hydrogels.

Summary: Composite films PVA-CS-Cur(x) (x = 0, 0.01, 0.06 and 0.12%) were obtained via vacuum-drying at 80 degrees C, improving the thermal stability, water-resistance, and mechanical property of films. The oxygen permeability of PVA-CS-Cur(x) showed dependence on test temperature and curcumin concentration. The films demonstrated excellent antibacterial capability and potential application in food decontamination.

Summary: The preparation method of hydrogels has a significant impact on their properties. In this study, PVA/HA hydrogels were prepared using autoclaving and glutaraldehyde addition methods. The autoclaved hydrogels exhibited better microstructure, swelling levels, and water retention capacity, while the glutaraldehyde-cross-linked hydrogels promoted plant growth. The release behavior of urea was also influenced by the preparation method.
