Latest detailed graphene technology roadmap release
Graphene is a two-dimensional crystal composed of a single layer of carbon atoms, which has been produced for the first time since 2004 and has caused a worldwide research boom. As graphene has excellent mechanical properties, electrical properties, thermal properties, etc., the material is expected to bring a new technological revolution in the semiconductor, energy, environmental, electronics, military and other fields. Many countries and regions such as the European Union, the United States, Singapore, and South Korea have conducted relevant research and implementation, and have made strategic deployments to relevant industries. At present, graphene materials are considered to be on the eve of industrialization breakthroughs. In the future, the new materials will influence human life and social development in ways that have aroused widespread expectations in the industry. It is against this background that the EU selected one of the flagship flagstone projects as one of the first flagship projects in January 2013. The project is expected to run for 10 years with a total investment of 1 billion euros. It aims to bring graphene and related layered materials from the laboratory into society, thus bringing a new revolution to many industries and promoting economic growth. The project included 76 academic and corporate research teams from 17 European countries and was divided into 11 scientific and technological themes.
Andrea C. Ferrari is the first author of this article, and also the chairman of the executive committee of the European Graphene flagship project, responsible for coordinating the management and execution of the entire project. This article is divided into background, basic research, health environment, production, electronic devices, spintronics, optoelectronic devices, sensors, flexible devices, energy storage and conversion, composite materials, biomedicine, conclusions and acknowledgements, etc. Cited 2334 articles. In this article, scientists outlined key issues related to the application of graphene and other related materials from basic research to related industries, highlighting the required research path for graphene from raw materials to possible industrial revolutions. At present, the application of graphene is mainly driven by the preparation and production of materials. Once the production of materials is mature, graphene will achieve a wide range of applications and impacts. In the end, the article emphasizes that the rapid development of graphene is based on the fact that it can be developed into novel applications rather than replacing existing materials. Graphene can only replace traditional materials when it is sufficiently competitive with existing industrial materials. In particular, the roadmap also talks about China’s progress in the field of graphene, and cites and draws on the work of a large number of Chinese scientists.
At the same time, the scientists emphasized that such a roadmap is not necessarily complete, but will also leave behind some areas of recent rapid development. Scientists plan to update the roadmap regularly over the next 10 years to keep abreast of the latest advances in the field of graphene materials.
On graphene-related issues, New Materials interviewed Dr. Li Xiaoming of the National Nano Center on-line:
1. Is graphene currently used on a large scale? What are the current applications?
Graphene is on the eve of a breakthrough in industrialization, and it is very likely that a specific scale application will be realized within the next few years. How the graphene will influence human life and social development in the future will already arouse the wide expectations of the industry and academia.
At present, the specific application of graphene is still in the research and development stage. This aspect is influenced by the preparation and production of graphene materials. On the one hand, it also depends on the performance and cost of the existing materials. A little bit different from the foreign countries is that China's institutions that master advanced graphene technology are still mainly in scientific research units, and the leading role and guiding role of companies in technology research and development is not prominent. In foreign countries, companies such as IBM, Samsung, Airbus, Nokia, and Sony have worked closely with research institutes at an early stage to guide the development of products such as composite materials, transparent conductive films, and flexible electrodes. From this perspective, domestic companies and scientific research institutions need to be able to further strengthen cooperation. In particular, companies can actively cooperate with scientific research institutions for long-term and close cooperation in the early development process of graphene in order to better realize the industrialization of core technologies. .
2. What is the future development trend of graphene?
In the short term, the limitations of graphene applications are mainly focused on the synthesis of materials. The industrialization of graphene is also currently limited to the development of the material itself. In certain applications, the specific quality of graphene is required, and the mass production of controllable graphene is still a great challenge at the present stage. In the near future, graphene is expected to take the lead in applications such as composite materials, transparent electrodes, flexible devices, and touch screens. In the long term, graphene is expected to find applications in sensing devices, high-frequency electronic devices, and biological fields only when high-quality graphene can be controlled at low cost and combined with existing mature semiconductor technologies.
3. Where is the outbreak of graphene in the future?
With the advent and development of new technologies, the explosion point of graphene materials should be synchronized with the trend of technological development. For example, graphene is well integrated and developed with existing technologies in the areas of information technology, energy conservation, detection and sensing, and flexible devices, and even plays a role in innovation and leadership. In particular, the emergence of a new type of material, combined with traditional materials and technologies, is often easier to apply and develop than alternative materials.
