　　Theoretical research on graphene began with... 1947 Year, to date there has been 70 a history spanning years. However, truly independently existing two-dimensional graphene crystals only emerged in 2004 Year: Professor of Astrophysics, University of Manchester, UK AndreK.Geim The leader’s research group was the first to obtain graphene using a micro-mechanical exfoliation method. Due to its outstanding mechanical, thermal, electrical, and magnetic properties, graphene holds great promise for widespread applications in high-performance nanoelectronic devices, composite materials, field-emission materials, gas sensors, energy storage, and other fields. As a result, graphene has rapidly become one of the hottest research topics in the fields of materials science and condensed matter physics in recent years.

　　Since graphene was first discovered, research on graphene technology has continuously achieved exciting breakthroughs. In the field of graphene preparation, how to achieve low-cost, high-quality, and controllable production has become a current research hotspot. ; In the application fields of graphene, breakthroughs are being made in multiple areas including semiconductors, electronics, materials, and bioengineering.

　　Graphene is currently still in the R&D stage, and countries around the world are in the patent-layout phase for this emerging material. There are no signs yet of industrial-scale production, and the entire industry chain has not yet taken shape. At present, the technologies used to produce graphene are immature, and consistent product quality has not yet been achieved. Moreover, the area of finished products is extremely small, making them unsuitable for industrial applications. However, the potential is enormous... 2000 Yuan / The attractive product prices and promising market prospects have kept all parties continuously engaged in graphene research.

　　The development of emerging technologies is inseparable from policy support and guidance. In 2010 Since the discoverers of graphene were awarded the Nobel Prize, not only has the global scientific community paid close attention, but governments around the world have also stepped up their support for graphene research and development, hoping to seize the initiative in this new round of competition for graphene research and industrialization. Among the major graphene powers, the European Union and its member states, as well as the United States, Japan, and South Korea, have been among the first to launch strategic initiatives, introducing various supportive policies and research funding programs, thus placing them at the forefront of global graphene research and industrialization.

　　Graphene has not yet been industrialized, and its selling price is extremely high. Currently, the domestic selling price is... 2000 Yuan / Exceeding several grams, it’s roughly ten times the price of gold. Thanks to its unique physical structure and properties, graphene is poised to bring revolutionary changes across multiple fields, and once mass production is achieved, it will undoubtedly become the next trillion-dollar industry.

　　Developed countries are focusing on the research, development, and application of graphene-based functional devices. In the future... 5-10 The global graphene market is set to enter a period of rapid growth this year. Regions such as the U.S., Europe, Japan, and South Korea have been intensively rolling out policies to support the R&D and industrial-scale application of graphene-based functional devices. Companies in Europe and the U.S. hold key positions throughout the global graphene industry chain, maintaining a leading edge in graphene preparation technologies, composite materials, and core electronic components. Meanwhile, the Asian graphene application market shows promising prospects.

　　The data shows that, 2016 The global market size for graphene this year is... 755 tens of thousands of U.S. dollars. As graphene preparation technologies continue to drive large-scale applications, the market will enter a period of rapid growth within five to ten years, and by... 2020 The annual market size could reach 3.85 hundreds of millions of dollars, 2025 The global scale is expected to reach annually. 21.03 hundred million dollars.

　　Based on the different properties and development challenges of graphene, we have summarized the following development pathways:

　　 ◆ First, graphene powder and film products now have the potential for mass production. Correspondingly, related fields such as conductive and thermally conductive additives, anti-corrosion and heat-dissipating materials, composite materials, and touch-screen applications are also expected to achieve breakthroughs at the earliest opportunity.

　　 ◆ Second, the properties of graphene—its high electrical conductivity, high specific capacity, and large specific surface area—have already been explored to enhance the energy density and charge-discharge rate of supercapacitors. ; Additionally, due to its light sensitivity being higher than that of ordinary sensors, 1000 Doubling the application of sensors is also expected to be achieved as a mid-term goal.

　　 ◆ Finally, the area with the greatest potential for graphene is its replacement of silicon as the foundational material for next-generation ultra-high-frequency transistors, which will be used in high-performance integrated circuits and novel nanoelectronic devices. The need to further increase computer speeds calls for even greater integration densities of components; however, silicon has already reached a bottleneck in terms of further size reduction. IBM The future 5 Will be invested this year 30 Billions of dollars are being invested in the deployment of post-silicon technologies, with graphene emerging as one of the key technological directions. However, since graphene itself is a conductor, single-layer graphene lacks a band gap. (Band Gap) It is unable to achieve the transistor switching function necessary for logic circuits, requiring either artificially introducing a bandgap or adopting composite materials—both of which significantly increase process complexity. As a result, widespread adoption in the microelectronics field remains some time away.
