Abstract :
Graphene oxide was prepared by a modified Hummers method in a Teflon-lined autoclave and then reduced by two different approaches. Alkaline reduction by sodium hydroxide as the control and synergetic reduction which combined sodium hydroxide and microwave irritation were conducted. The products were characterised by transmission electron microscopy, X-ray diffraction, thermo-gravimetric analysis, Fourier transform infrared spectroscopy and by atomic force microscopy. Results showed that the synergetic method possessed higher efficiency. Moreover, the as-prepared samples were monolayers (about 0.8 nm) and could decrease the solubility of ethyl cellulose in ethanol.
