3 materials1 process step
Graphite is oxidized at about 50°C for about 15 hours using an acid mixture containing permanganate oxidant to produce a 2D layer-structured graphene oxide (GO).
3 materials1 process step
The layer-structured GO is heated to 100-120°C for 5-20 minutes (optimized at 15 minutes) in the same reaction vessel without removal, causing removal of oxygen functional groups and simultaneous covalent interconnection via ether and ester groups (formed from -OH and -COOH groups), yielding 3D IC-RGO with interlayer distance of ~0.37 nm and approximately 5 layers (crystallite size Lc = 1.81 nm by XRD). The product is rinsed with HCl, water and ethanol.
Performance values and ranges asserted in the specification or claims.
