(Summary description)Graphene powder is a hexagonal two-dimensional carbon nano material with honeycomb lattice, which is separated from graphite by micromechanical stripping. It is a two-dimensional crystal composed of a layer of carbon atoms. Compared with other organic polymer materials, graphene has unique atomic structure and mechanical properties. Its bonds link with other carbon atoms to form a hexagonal honeycomb layered structure. The pz orbital of each carbon atom perpendicular to the layer plane can form polyatomic large bonds throughout the layer, so it has excellent electrical conductivity and optical properties. The theoretical Young's modulus of graphene is 1.0 TPa, and the inherent tensile strength is 130 Gpa, which is one of the materials with very high strength known. At the same time, it has good toughness and can bend, and is known as the "king of new materials" and "black gold".

Information

Graphene powder is a hexagonal two-dimensional carbon nano material with honeycomb lattice, which is separated from graphite by micromechanical stripping. It is a two-dimensional crystal composed of a layer of carbon atoms. Compared with other organic polymer materials, graphene has unique atomic structure and mechanical properties. Its bonds link with other carbon atoms to form a hexagonal honeycomb layered structure. The pz orbital of each carbon atom perpendicular to the layer plane can form polyatomic large bonds throughout the layer, so it has excellent electrical conductivity and optical properties. The theoretical Young's modulus of graphene is 1.0 TPa, and the inherent tensile strength is 130 Gpa, which is one of the materials with very high strength known. At the same time, it has good toughness and can bend, and is known as the "king of new materials" and "black gold".

According to the number of layers, graphene powder can be divided into single-layer graphene, double-layer graphene, few layers graphene and multilayer graphene; It can be divided into graphene oxide, hydrogen fossil graphene and fluorofossil graphene according to its functional form; According to the external shape, it can be divided into sheet, film, quantum dot, nano ribbon or three-dimensional shape. Graphene powder has excellent material properties such as superconductivity, good thermal conductivity, good light transmittance, solubility, permeability, high flexibility and high strength. Because of these properties, it can be used in a wide range of fields, mainly basic disciplines, new energy batteries, flexible displays, sensors and composite materials.

Graphene powder has a wide range of downstream applications. It shows excellent performance and can be used in semiconductor devices, battery electrode materials, transparent liquid crystal displays, capacitors, sensors, transistors, etc. It has made a series of important progress in chemistry, materials, physics, biology, environment, energy and other disciplines. The upstream of graphene is graphite, while the downstream is mainly used for new energy batteries, coatings, flexible screens and sensors.

The research, application and development of graphene powder continue to heat up. Graphite and graphene related materials are widely used in battery electrode materials, semiconductor devices, transparent liquid crystal displays, sensors, capacitors, transistors, etc. In view of the excellent performance and potential application value of graphene materials, a series of important advances have been made in chemistry, materials, physics, biology, environment, energy and other disciplines.

The downstream application of graphene is mainly divided into two aspects: one is the downstream application of graphene film, and the other is the downstream application of graphene powder. Graphene film can be used in flexible displays and sensors, and graphene powder can be used in new energy batteries, composite materials, lithium batteries, etc. At present, graphene is widely used in the downstream field of new energy related fields, which is the main driving force for ultra-high growth of the industry. The application of graphene in composite materials, anti-corrosion coatings, biosensors and other fields has also attracted much attention. Energy conservation, environmental protection, flexible display of electronic information and other fields have also been involved.
