Method for quickly preparing reduced graphene by using microwaves
2011
The invention relates to a method for quickly preparing reduced graphene by using microwaves, which comprises the following steps: grinding graphite oxide into fine powder of which the particle size is 1-100 micrometers, and treating the graphite oxide with 100-2000W microwave radiation for 0.1-200 minutes in a vacuum degree of 0.01-10Pa or in a protective atmosphere, so that the graphite oxide quickly expands, thereby obtaining the reduced graphene. The invention has the advantages of simple preparation process and low preparation temperature, and is easy to operate.
