Mechanical and Thermal Properties Enhancement and Swelling Behavior of Bacterial Cellulose/Collagen/Polyvinyl Alcohol Nanofiber Hydrogel Film

Composite hydrogel films of bacterial cellulose/collagen/polyvinyl alcohol were prepared by soaking method using bacterial cellulose hydrogel (BC) was as the base material, collagen (COL) and polyvinyl alcohol (PVA) were introduced as the reinforcement material to further improve the tensile strength especially elongation at break. Morphology, mechanical property, and thermal stability of composite hydrogel films were also investigated. The...
