Negative Swelling and Mechanical Self‐Enhancement TAFe@PVA Photothermal Hydrogel Mediated Via Semi‐Crystallization for Medical Implants

Advanced Functional Materials, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 15, 2025

Abstract Medical implants, important consumables, significantly promote patients’ healthcare, but still face challenges of foreign body responses and bacterial infection. Hydrogels can be ideal alternative materials, however, a few them meet the requirements. Herein, TAFe@PVA photothermal hydrogel integrating with negative swelling, long‐term stability, antibacterial, anti‐adhesion, tissue mechanical matching is developed to solve these issues. The crosslinked by H‐bonds microcrystal domains which both enhanced cations or anions based on Hofmeister effect, showing unique swelling self‐enhancement performances in physiological fluid. Attributing self‐polymerization tannic acid (TA) polyvinyl alcohol (PVA) molecular networks, TAFe complexes strongly locked PVA reaching stability. also exhibits great biocompatibility, anti‐oxidation, anti‐bacterial performances, comparing traditional implant material. Since better match skin tissues, fewer macrophages myofibroblasts are activated, depresses unexpected responses. Finally, as effectively abdominal adhesions after operation defects healing. This study introduces promising implant, potentially extends hydrogels wider medical applications.
