Description

Graphene Oxide Thin Films are composed of graphene oxide (GO), a novel advanced material that consists of graphene, a single atom thick layer of carbon atoms, with various oxygen-containing functionalities. Graphene oxide and reduced graphene oxide (r-GO) thin films are available on various substrates including glass, quartz, PET, and Si/SiO2 substrate wafers.
