Interfacial Combination and Mechanical Properties of BC/PVA Multilayer Composite Hydrogels
Bacterial cellulose (BC)/Poly vinyl alcohol (PVA) multilayer composite hydrogels were prepared by freezing and thawing. The mechanical properties of the composite were investigated in this paper with different mass percent of PVA, number of BC layers. Scanning electron microscope (SEM) was used to characterize the fracture characterizations of the composite and the interface structure between BC membrane and PVA hydrogel. It was found that composite hydrogels with 15wt% PVA and 2 layers BC membranes exhibit excellent mechanical properties and wonderful bonding effect of the interface.
