Abstract
Bacterial cellulose/poly(vinyl alcohol) (BC/PVA) composite membranes using BC as the reinforcement and PVA as the matrix material were prepared in supersaturation of sodium chloride and crosslinked with glutaraldehyde, and characterized by attenuated total reflection Fourier-transform infrared spectroscopy, equilibrium swelling ratio tests, and mechanical properties tests. The chemical crosslinking degree of the membranes was determined by titration method, and it could be controlled by crosslinking time. The effects of the chemical crosslinking degree on properties of the BC/PVA composite membranes were investigated. It was demonstrated that chemical crosslinking was formed between BC/PVA and glutaraldehyde. As a result, the chemically crosslinked BC/PVA composite membranes exhibited some promising characteristics, such as appropriate equilibrium swelling ratio, good mechanical strength, and obvious effect of chemical crosslinking degree. Furthermore, the equilibrium swelling ratio and mechanical properties of the BC/PVA composite membranes were obviously affected by the BC content as well.
