Graphene oxide and reduced graphene oxide

Graphene oxide is obtained chemically in several steps from the initial raw material - graphite. At the first stage, graphite is made into graphite oxide by intercalation of acid and chemical reagents into the interlayer space of graphite (modified Hammers method). At the second stage, the distance between the layers of graphite oxide is expanded and a suspension of graphene oxide is obtained - individual single-layer particles. Then it is dried to obtain graphene oxide powder. Or, the oxide groups are chemically removed to produce reduced graphene oxide.

Graphene oxide and reduced graphene oxide are used in the following areas:
  • supercapacitors
  • filters and membranes
  • biosensors
  • composite materials
  • antibacterial coatings
