Abstract
Methods of preparing reduced graphene oxide and reduced graphene oxide-polymer composites. The methods include covalently binding a halogen-substituted aromatic compounds to a graphene oxide and heat treating the graphene oxide with the halogen-substituted aromatic compounds covalently bound thereto at a low temperature, for example, 450° C. or less. By using the methods, reduced graphene oxide and reduced graphene oxide-polymer composites that have high electrical conductivities (e.g., 30,000 S/m or more) may be obtained.
