Graphene is a two-dimensional carbon nanomaterial composed of carbon atoms and sp2 hybrid orbitals composed of hexagonal honeycomb crystals. The single layer of graphene is composed of a dense layer of carbon six elements. The ring structure, with a thickness of about 0.335 nm, is by far the thinnest two-dimensional carbon nanomaterial.
Graphene material has many special properties due to its special structure, excellent electrical properties, excellent mechanical properties, extremely high thermal conductivity, large specific surface area, excellent barrier properties, etc., making it impossible for traditional materials in many fields The application value of the enterprise is therefore called "the king of new materials". At the same time, it has aroused great interest in the scientific community and become a hot spot in materials science research, and graphene-related industries have also appeared.
Graphene can be applied in a very broad field, mainly concentrated in energy, environment, electronics, chemical industry and other industries, in lithium battery materials, high-performance composite materials, supercapacitors, OLEDs, flexible screens, sensors, chips, coatings, adsorption, water purification And other fields have great application prospects.
As the king of new materials, graphene has attracted much attention since its birth. After ten years of development, the development of graphene in China has become rational and enterprises have diverged. Some enterprises have grown into leading companies in the field of graphene in China and even in the world; such as XMKN Graphene Technology Company, SDLT Nanotechnology Company, JS Carbon Technology, etc., the earliest batch of graphene companies in China.
In particular, after the experts who studied graphene won the Nobel Prize in Physics in 2010, the number of graphene companies continued to increase, and the application of graphene materials gradually expanded, which attracted the attention of the whole society.
This year is the tenth anniversary of China’s graphene industrialization and the tenth anniversary of the graphene project’s Nobel Prize. XMKN Graphene Technology, the strongest company in the graphene industry, has ushered in its tenth industrialization of graphene The anniversary is an important milestone in the development of the graphene industry.
As the leading graphene powder, graphene composite conductive agent, graphene-based high thermal conductivity carbon plastic alloy, and graphene radiator manufacturer in China and even the world, XMKN adheres to the industrial preparation and industrial application of graphene physical method for ten years to innovate As a driving force for productivity, a large amount of scientific research funds are invested every year for product development and process transformation, reducing production costs and improving product quality. At the same time, in terms of graphene preparation and "graphene+" application products, it has strong technical and industrial strength in new energy, high-performance thermally conductive composite materials, functional coatings and plastic modification.
XMKN recently launched its latest product: graphene conductive film.
The transparent conductive film is a conductive film with high transparency. The commonly used transparent conductive film on the market is ITO (tin-doped indium oxide), etc. The production of this type of film requires expensive vacuum coating equipment and flexible technology for the future market Requirements, the development space for such films is very limited.
The newly launched graphene is a new generation of flexible transparent conductive film materials. XMKN has successfully developed a process for preparing graphene transparent conductive film using graphite oxide as a raw material. The graphene transparent film prepared by this technology has simple process and low cost, and has great application potential in the fields of mobile phone touch screen, LED display and thin-film solar cell. .
Technical characteristics and indicators:
1. The thickness of the graphene film prepared by this technology is 10-20 nm, the visible light transmittance is greater than 85%; the electrical conductivity is 455S/cm;
2. This technology can form a uniform and continuous graphene film; 3. This technology can prepare large-area graphene film;
4.This technology is simple and cheap.
