Nanocellulose fibres can be hand-spun from different intermediate states, such as nanocellulose paper and filter cake, which are made from the BC suspension as well as wet pellicle (WP) and dry pellicle (DP) from BC pellicles. In this study, it can be concluded that increasing the hanging weight can increase the Young’s modulus and the tensile strength of fibres. Nanofibres produced from BC pellicles as raw material have better performance than those made from BC suspension. The best properties obtained from the fibres produced from wet pellicles and suspended to a 100g hanging weight upon drying are Young’s modulus (33.8 GPa), tensile strength (610 MPa) and elongation at break (3.6%).

The composites of graphene oxide/ Fe2O3-nanotubes (GO/ Fe2O3-NTs) have been fabricated through a facile one-step hydrothermal method. Fe2O3-NTs crystallines were homogeneously distributed on GO, which have been confirmed by transmission electron microscopy analysis (TEM). The structure, composition and electrochemical properties of GO/ Fe2O3-NTs composites were investigated by means of selective-area electron diffraction (SAED), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), Raman spectra, cyclic voltammogram (CV) curves and galvanostatic charge–discharge curves. GO/ Fe2O3-NTs composites exhibit a high specific capacitance of 133.2 Fg-1in 1 M Li2SO4electrolyte. In addition, the GO/ Fe2O3-NTs composites electrode shows good long-term cycle stability (only 9% decrease of the specific capacitance is observed after 1000 charge–discharge cycles).
