Recently, the ministry held a symposium, graphene industry development with all parties on behalf of the mission of graphene proposed innovation center function orientation and operation mode.
Since 2012, when the country issued documents clearly put forward to support the graphene after the development of new materials, graphene is frequently affected by policy to take care of, our country was introduced in 2015, the "made in China 2025" key areas technology roadmap ", "about accelerating the development of graphene industry innovation several opinions such as good file. With graphene innovation center will be built, the industrialization of graphene is expected to further development of our country, one hundred billion yuan of industrial scale is worth looking forward to.
"Magic material graphene advantage.
Graphene is an amazing new nanoscale materials, has good light penetration, high thermal conductivity, low resistivity, high electron mobility, high mechanical strength characteristics, can play effective performance in many application fields to replace the original material (such as) has replaced the silicon, become the "king of the 21st century new material".
The application of graphene technology field
The application of graphene technology field
Batteries, for example, compared with the traditional electrode materials, graphene has high volume density, high power density, cell structure and better performance optimization and other advantages. Graphene used in lithium batteries, can greatly improve the battery capacity, for the new energy vehicles to solve the problem range.
In nanjing university of science and technology team, a new study out of the hybridization of graphite oxide and its application in the energy "of the new achievements, greatly improving the lithium battery energy storage, can improve the battery life is short, life is not long, will drive the lithium battery industry and the development of new energy vehicles and other related industry.
Based on graphene excellent performance, all countries in the spare no effort to promote the development of industrialization of graphene, graphene related technology research and development has been listed in the United States, Britain, Japan and South Korea key support projects in countries such as new material field.
Graphene industry begun to take shape in China
For frequent policy, domestic graphene emerging research and development, in technology research, in 2011, domestic 278 papers related to the graphene, for 494, 2012, 2013 in 718, rose to 914, 2014, 2015 to 1239; Technology patents. At present our country in the world have applied for more than 2200 graphene patent technology, about a third of global graphene patent technology.
The application of graphene technology field
At the same time, the graphene industry has started.
Industry scale, our country has formed in jiangsu province, changzhou, wuxi, nanjing, etc) as the center, ningbo, Qingdao, chongqing, deyang, hebei, Beijing and other places scattered active development pattern. Downstream of the industrial chain, the company is in the majority. At present, the preparation of graphene industry already has more than 50 and related application development enterprise, the market competition is mainly concentrated in graphene scale two aspects of preparation technology and dock with the downstream commercial application.
However, as an emerging industry, the process of industrialization of graphene summary there are still many deficiencies.
The graphene is still in the early stage of industrialization, the good not completely realize the large-scale applications of graphene, the largest demand for graphene products market is still a scientific research institutions and a small number of manufacturers. Due to the downstream demand is not up, the majority of graphene enterprise is still unable to find a stable business model and profit model.
The application of graphene technology field
Hinder the graphene large-scale commercial application of the difficulty lies in two aspects: technology, how to mass to the preparation of large area, good stability, high quality graphene is one of the difficulties, at present the whole industry is still in the stage of product development, only a handful of companies to large-scale preparation of high quality graphene, the impact of defective rate on the industry application extension of the downstream; Sales level, industry enterprise is still unable to stable profit, how to integrate the upstream and downstream industry chain, namely the promotion or sales will be the key to the development of graphene industry.
Close shot and $5 billion to $one hundred billion prospects three trends is remarkable
, a research firm, points out that under the policy is good, the industrialization of graphene in 2016 will mark the key year, market space is expected to exceed 5 billion yuan. The electronic equipment heat dissipation material will have 3.6 billion yuan, conductive additives for 800 million yuan, transparent conductive film 300 million yuan 200 million yuan 100 million yuan and military materials, super capacitor.
According to the "made in China 2025" key areas technology roadmap ", in 2020 the graphene need billions industry scale formation, in 2025 the overall industry breakthrough billions, it requires the graphene industry development on the basis of the current "great leap forward". Under this background, the graphene industry will have the following three trends:
With the development of the level of preparation of graphene and graphene application technology development, graphene materials can be used in the field of more downstream products and. Is expected to around 2024, graphene devices are expected to replace complementary metal oxide semiconductor (CMOS) devices, in nanoscale electronic devices, photoelectrochemical cell, ultralight aircraft materials applied research field;
Consumer electronics applications will into graphene technology to overcome the main direction. Graphene preparation and application of technical level development complement each other, look at the current level of development, the quality of the applications of graphene in the field of electronic components and technical requirements, the highest and most difficult to achieve, we expect its application in 10 years or so; Applications of graphene in the consumer electronics main preparation technology to overcome difficulties, it is also the most hot spots in the direction of the graphene research at present, we expect the preparation technology in the next 1-2 years will have tu;
Graphene research and industrialization development is on the rise. From the point of graphene patent field distribution, its layout application technology research hot spots include: graphene as lithium ion battery electrode materials, solar battery electrode materials, preparation of thin film transistor, sensor, semiconductor devices, composite material preparation, transparent touch screen, transparent electrode, etc.
