Abstract
The present invention relates to a method for preparing graphene, and more particularly to a method of preparing graphene sheets, which can prepare graphene sheets from a turbostratic graphitic structure such as carbon fiber in higher yield without using a strong oxidizing agent, and to graphene sheets prepared thereby.
Claims18
A method for preparing graphene sheets, the method comprising the steps of:
- oxidizing a graphitic structure having a turbostratic structure;
- subjecting the oxidized graphitic structure to microwave irradiation;
- and
- sonicating a few-layer graphene obtained by the microwave irradiation step.
