    Research output: Patent


    This invention relates to a method for the production of graphene oxide and its use in various applications. The invention provides a method for the preparation of graphene oxide which involves treating a mixture of graphene oxide and impurities with a solution of a base. The impurities in the graphene oxide include oxygen-containing species that are associated with it i.e. bound to the graphene oxide but which are not covalently bonded to the graphene. The graphene oxide of the present invention has improved purity relative to the poorly characterised graphene oxide that is produced by existing methods.
