Product Overview

Graphene oxide (GO) is a type of derivative in the process of graphite to graphene transformation, which is a layered material obtained by ultrasonic exfoliation, dispersion, and grinding after graphite oxidation. It was discovered by Oxford University chemist Benjamin Brodie in 1859.
Graphene oxide belongs to 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 method, solvent exfoliation method, chemical vapor deposition method, micro mechanical exfoliation method, metal surface epitaxy method, etc. Among them, the most convenient, low-cost, and large-scale production method is oxidation method. The oxidation method can be divided into Staudenmaier method, Brodie method, Hummers method, Offering 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 energy storage, batteries, photocatalysis, biomedical, sensors, water treatment, and other fields, and is widely used in modified polystyrene, polypropylene, polyurethane, polylactic acid, polymethyl methacrylate and other foaming materials.

Application Fields

Graphene oxide is a novel carbon material with excellent performance, rich in surface functional groups, and widely used in the following fields:
Electronic products: Many electronic devices can be manufactured using graphene oxide as a basic material for one of the components, and field-effect transistors using reduced graphene oxide have been used as chemical sensors and biosensors.
Energy Reserve: Nanocomposite materials that reduce graphene oxide have been used for high-capacity energy storage in lithium-ion batteries. Reduced graphene oxide with a large surface area can be used as an energy storage material in supercapacitors.
Biomedical: One application of graphene oxide in the biomedical field is as an element in drug delivery structures. Functionalized nano graphene oxide can be used for targeted distribution of anticancer drugs.
Biosensors: Graphene oxide, as a fluorescence quenching material, can be applied to biosensors with fluorescence resonance energy transfer effects.
Environmental protection: Graphene oxide based composite materials can be used to treat harmful gases and convert air pollutants into useful energy resources.

Product Features

The single-layer graphene oxide dispersion provided by Xianfeng Nano is prepared by ultrasonic dispersion of single-layer graphene oxide in a solvent. There are three specifications of sheet sizes: greater than 500nm, less than 500nm, and 50-200nm, which have the following characteristics:
1. Composed of single atomic layers: with an average thickness of 0.8-1.2nm and a monolayer rate of 99%.
2. Good dispersibility: Graphene oxide has good dispersibility in aqueous media, which makes it easier to mix with other materials in many applications.
3. Easy functionalization: Its surface contains various oxygen-containing functional groups, such as hydroxyl, carboxyl, and epoxy groups, which can be modified through chemical reactions to endow graphene oxide with new properties.
4. Multiple active sites: During the preparation process, a large number of active sites are generated, which is beneficial for interacting with other substances.
5. Special optical properties: Graphene oxide has a certain absorption in the visible light range, and its optical properties can be adjusted by changing its structure and functional groups.
6. Electrical properties: Although graphene oxide itself is an insulator, it can restore certain conductivity after reduction treatment, and its electrical properties can also be controlled through doping and other methods.
