NON-COVALENT MAGNETIC GRAPHENE OXIDE COMPOSITE MATERIAL AND METHOD OF PRODUCTION THEREOF

摘要

The present invention provides in a first aspect a method of preparing a magnetic graphene oxide composite material, comprising: forming a dispersion of graphene oxide and the magnetic material within a dispersant solution; and controlling the pH of the dispersant solution to cause the graphene oxide and magnetic material to have different surface charges, thereby forming a magnetic graphene oxide composite material comprising a non-covalent complex of graphene oxide and a magnetic material.
