Abstract

A simple and efficient wet-chemical strategy was developed to form graphene oxide scrolls around multi-walled carbon nanotube templates through covalent bond formation. Scanning electron microscopy, atomic force microscopy, transmission electron microscopy and dynamic light scattering measurements confirmed the scrolled conformation of graphene oxide sheets while Fourier transform infrared spectroscopy and X-ray photoelectron data indicated the formation of covalent bonds between the scrolled sheets and the nanotubes. Conformational changes of the graphene oxide sheets were also monitored by Raman spectroscopy. All the data suggested successful formation of graphene oxide scrolls with multi-walled carbon nanotube templates.
