Product Overview
Graphene oxide (GO), also known as graphene oxide, is a type of derivative in the process of transforming graphite into graphene. It is a layered material obtained by ultrasonic exfoliation, dispersion, and pulverization of oxidized graphite. It was discovered by Oxford University chemist Benjamin Brodie in 1859.
Graphene oxide is a two-dimensional structured nanomaterial with a single atomic layer thickness, composed of sp2 and sp3 hybridized carbon atoms. Its structure contains various oxygen-containing hydrophilic functional groups such as hydroxyl, carboxyl, and epoxy groups, and has good dispersibility in aqueous media.
The main methods for preparing graphene oxide include oxidation, solvent exfoliation, chemical vapor deposition, micro mechanical exfoliation, metal surface epitaxy, etc. Among them, the most simple, low-cost, and capable of large-scale production method is oxidation. Oxidation methods are divided into Staudenmaier method, Brodie method, Hummers method, Offerman method, etc.
Due to its low preparation cost, good film-forming properties, large specific surface area, and easy functionalization, graphene oxide has broad application prospects in fields such as energy storage, batteries, photocatalysis, biomedicine, sensors, water treatment, and is widely used in modified polystyrene, polypropylene, polyurethane, polylactic acid, polymethyl methacrylate and other foaming materials.
