Graphene material has excellent performance and wide application, and has broad market space and sustained growth potential. In the long term, with the reduction of preparation costs and the development of product applications, the permeability and use of graphene materials are expected to rise rapidly.
Graphene: the king of new materials
Graphene is a kind of two-dimensional carbon nanomaterial with hexagonal honeycomb lattice formed by carbon atoms in sp2 hybrid orbit. Single-layer graphene is composed of a dense layer of carbon six-membered rings. Its thickness is about 0.335nm, which is the thinnest two-dimensional carbon nanomaterial so far.
In fact, graphene already exists in nature, but it is difficult to peel out the single layer structure. Graphene is graphite layer by layer. The graphite with a thickness of 1 mm contains about 3 million layers of graphene.
Graphene materials have special properties that other materials do not have, such as excellent electrical properties, excellent mechanical properties, extremely high thermal conductivity, ultra-large specific surface area, excellent barrier properties, etc., which make them have application value in many fields that traditional materials cannot match, so they are called “the king of new materials”.
Graphene can be applied in a wide range of fields, mainly in energy, environment, electronics, chemical and other industries, especially in the fields of lithium battery materials, supercapacitors, OLEDs, flexible screens, sensors, chips and other fields in the electronic industry, as well as in the fields of coatings, adsorption, desalination and other fields in the chemical industry.
Will graphene, the “king of new materials”, lead to the next trillion-yuan new market?
The application market has huge development potential, which will have a “disruptive” impact on the future industrial development
Graphene has excellent performance in light, electricity, heat, power and other aspects, has great application potential and can be widely used as a new material for economic and social development. For example, the 8-14 micron far-infrared ray generated by graphene during heating is the most suitable wave band for human health. Therefore, carrying graphene products with such functions is like inviting a acupuncture and moxibustion masseur to regulate the immune system of the meridians. Undoubtedly, this is a good news for computer users, mobile phone users, drivers who have been driving for a long time and people with cervical spondylosis.
In addition, only 1cm thick graphene battery can fully charge the smart phone in 5 minutes, which can be called the king of charging; Foldable LED transparent flexible screen can watch movies, make phone calls and browse web pages; Line RFID tags can be printed on ordinary paper and folded 150000 times without loss of performance. According to the data, China’s graphite ore reserves are more than 55 million tons, accounting for about 77% of the world’s total. At present, there is a certain foundation for the development of graphene industry in China. It is reported that the number of patents in the graphene field in China accounts for about 40% of the world’s total, and China has made certain achievements in industrialization. At present, the processing cost of graphene has been reduced to 1/10 of 2011, and the excellent rate and consistency have also been greatly improved, which is conducive to the expansion and development of downstream application fields.
Graphene has good application prospects in energy equipment, transportation, aerospace, marine equipment and other products. It is reported that the annual production capacity of graphene in the world has reached 100 tons at present and will reach 1000 tons in the next 5-10 years. By 2020, the global graphene market will exceed 100 billion yuan. Among them, China accounts for 50-80%. China will play a leading and core role in the global graphene industry. By 2020, the scale of graphene industrialization will make a breakthrough.
Among them, the market scale of lithium batteries and supercapacitors in the new energy industry will exceed 53.4 billion yuan. In the field of flexible display and wearable in the electronic information industry, the market size will exceed 26.7 billion yuan. In the field of plastics, rubber, paint and conductive ink in the composite material market, the scale will exceed 37.2 billion yuan. In the field of energy conservation and environmental protection, it will exceed 9 billion yuan. In the field of thermal management, the market scale of electronic product cooling film, LED cooling material, graphene heating film and other products will exceed 34.1 billion yuan. In the field of biomedicine, graphene will be applied to biosafety, nano-drug delivery system, gene therapy, biological monitoring, and biological imaging and diagnosis, and the market scale will exceed 9.1 billion yuan.
Graphene is considered to have a “subversive” impact on the future industrial development, and graphite is one of the important raw materials for preparing graphene. At present, the preparation of graphene from natural graphite is the most commercialized way. The development of graphene industry has directly triggered the development boom of graphite resources. With the continuous breakthrough of industrial technology and the continuous development of various downstream applications, the commercial application process of graphene materials will also continue to accelerate. In the future, graphene application market has great development potential, which will lead to a trillion-yuan new market.
