Fiber-reinforced polyvinyl alcohol hydrogel via <i>in situ</i> fiber formation

Abstract Polyvinyl alcohol (PVA) hydrogels have been extensively investigated for drug release, artificial cartilage, biosensing, and other applications owing to their good chemical stability, biocompatibility, high water absorption, ease of processing. However, the conventional hydrogel preparation method is complex energy-intensive, mechanical performance pure PVA poor, which severely limits its application in related fields. In this study, a was functionally modified using polybutylene succinate (PBS) nanofibers prepared situ fiber-forming technology fabricate PBS-enhanced composite hydrogel. The strength PBS/PVA fabricated study 3.88 MPa, 4.94 times that hydrogel; thus, effectively improved. used novel straightforward. Moreover, resulting materials are biodegradable non-toxic. Compared methods, has advantages conserving resources being environmentally friendly.
