摘要

This study presents a novel one-step synthesis method for producing green, flexible, and stretchable superabsorbent polymer sheets with high-performance antibacterial properties, utilizing an energy-efficient and sustainable solution polymerization approach. Acrylic acid was partially neutralized and crosslinked with polyethylene glycol diacrylate, while ethylene glycol was a reactive solvent. Quaternary ammonium compounds (CTAB and TBAB) were incorporated as antibacterial agents, with UV initiation enabling rapid polymerization at room temperature. The resulting SAPs exhibited exceptional swelling capacities (up to 79.8 g/g in water) and mechanical properties, including elongation at break up to 294.2%, attributed to the plasticizing effects of CTAB and TBAB. Antibacterial assays demonstrated > 99.9% bacterial reduction within 1–3 h for CTAB-containing SAPs. The elimination of energy-intensive drying and surface crosslinking steps highlights the scalability and sustainability of this method. Biocompatibility tests confirmed cell viability > 84%, meeting ISO 10993–5 standards. This technology offers a promising pathway for advanced applications in hygiene products and regenerative medicine.
