The Electrical Property of Large Few Layer Graphene Flakes Obtained by Microwaves Assisted Exfoliation of Expanded Graphite

Few layer graphene (FLG) was synthesized by µ-wave assisted exfoliation of expanded graphite in toluene with an overall yield from c.a. 7% to 20%. A significant difference in the absorption of µ-waves by the expanded graphite and toluene allowed a rapid heating of the medium. The number of FLG sheet...

Descripción
Sumario:Few layer graphene (FLG) was synthesized by µ-wave assisted exfoliation of expanded graphite in toluene with an overall yield from c.a. 7% to 20%. A significant difference in the absorption of µ-waves by the expanded graphite and toluene allowed a rapid heating of the medium. The number of FLG sheets varies from 3 to 12, while the lateral size of the sheets exceeds few µms. The obtained FLG exhibits very low resistance with average value of 1.6 kΩ (500 Ω minimum) which is comparable to that of high quality graphenes synthesized by CVD methods, and lower than numbers of exfoliated graphenes.
