  • Method for the synthesis of graphene oxide
    Patent number: 10336619
    Abstract: Graphene oxide is synthesized by chemical treatment of graphite using only H2SO4, KMnO4, H2O2 and/or H2O as reagents. Graphene oxide films obtained using the method disclosed herein were characterized using various analytical techniques. These analytical techniques confirmed the creation of single to few layer graphene oxide with relatively large lateral size distribution using the method disclosed herein.
    Type: Grant
    Filed: July 27, 2016
    Date of Patent: July 2, 2019
    Assignee: Sri Lanka Institute of Nanotechnology (PVT) Ltd.
