Development of Scalable Elastic Gelatin Hydrogel Films Crosslinked with Waterborne Polyurethane for Enhanced Mechanical Properties and Strain Recovery

Gels, Journal Year: 2025, Volume and Issue: 11(1), P. 49 - 49

Published: Jan. 8, 2025

Exploiting novel crosslinking chemistry, this study pioneers the use of waterborne polyurethane (WPU) to chemically crosslink porcine-derived gelatin, producing enhanced gelatin hydrogel films through a solvent-casting method. Our innovative approach harnesses reactive isocyanate groups WPU, coupling them effectively with gelatin's hydroxyl and primary amino form robust urea urethane linkages within matrix. This method not only preserves intrinsic elasticity but also significantly augments films' tensile strength strain. Comprehensive characterizations these pre-formed reaction mixtures were conducted using viscosity measurements, Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA), universal testing machine (UTM) for tensile-recovery assessments, alongside evaluations their biocompatibility. The results demonstrated reduction in pore size an increase WPU concentration from 2 6% developed hydrogels decrease equilibrium swelling ratio 15% 9%, respectively. Further, exhibited highest stress both dry wet state. formed blend growth proliferation CCD-986K (fibroblast) CCD-1102 (keratinocyte) cells up 5 days co-culturing. indicate notable enhancement mechanical properties biocompatibility upon introduction positioning as superior candidates biomedical applications such tissue engineering wound dressing.
