Effect of Expansion Temperature of Expandable Graphite on Anti-Friction Effect of Graphite Nonasheets from Sonicating Expanded Graphite

Abstract:

Three graphite nanosheets were prepared by sonicating three expanded graphites that were formed by rapidly heating expandable graphite at 600, 800 and 1000 °C, respectively. The graphite nanosheets were characterized by scanning electron microscope. The anti-friction effects of the graphite nanosheets used as lubricating additives were investigated. The results show that the size of the graphite nanosheets decreases with increasing the temperature of expandable graphite. The graphite nanosheets have an obvious anti-friction effect, and the effect is related to the heating temperature.
