| Abstract | In this study, highly ordered, flexible, homogeneous and reinforced microcrystalline cellulose (MCC)–graphene oxide (GO) composite films regenerated from MCC/1-butyl-3-methylimidazolium chloride ([Bmim]Cl) solutions were prepared, and their nanostructures, thermal stability and mechanical properties were investigated by Fourier-transform infrared spectra, X-ray diffraction spectra, scanning electron microscopy images, thermal gravimetric analyses and tensile strength measurements. Moreover, the effect of the dispersion state of GO in MCC/[Bmim]Cl solutions with varying GO contents was studied by rheological tests. The mechanical properties of composite films could be remarkably improved over those of pure MCC film and there is a close relationship between the dispersion state and reinforcement effect of GO. Specifically, in comparison with pure MCC film, the composite film containing 0.5 wt% of GO exhibits a 64.7% enhancement in tensile strength and an 85.1% enhancement in strain-to-failure whereas the mechanical properties of the composite films are inferior to that of pure MCC film when the GO content is higher than 1 wt%. |
