Efficient reduction of graphite oxide by chemical reduction and microwave irradiation

Complete reduction of graphene oxide flakes produced from graphite in a mass-production manner is highly interesting. In a joint research project between the Ångström Laboratory and Fudan University in Shanghai, a reduction procedure that combines the ordinary chemical method with microwave treatment is investigated. The electrical conductivity of a reduced graphene oxide thin film is nearly two orders of magnitude higher than that obtained by the chemical method alone.
