| Abstract: | The expanded graphite as raw material was oxided by liquid stripping method and modified hummers graphite oxide process. And the hydrazine reduction of pre-reduction and high temperature were carried out to graphite oxide and the productions were charactered by SEM, TEM, Raman and EDX analysis. The results indicated that high-quality, high density, high-volume graphene was obtained. The tribological behavior of graphene as lubricant additive is investigated by an oscillating SRV testing machine, and the wear resistance mechanism is discussed. |
