Graphene, as the thinnest, toughest and best conductive nano material found at present. It is a two-dimensional crystal composed of carbon atoms stripped from graphite material with only one layer of atom thickness. Known as “black gold”, it is “the king of new materials”. Scientists even predicted that graphene “will completely change the 21st century”.

Graphene is the first two-dimensional crystal made of carbon atoms only one atom thick, stripped from graphite. Graphene is both the thinnest material and the strongest, breaking 200 times stronger than the best steel. At the same time, it has good elasticity, stretching up to 20% of its size. It is the thinnest and strongest material in nature, and a hammock made from one square meter of graphene could support a cat weighing less than one milligram. One of graphene’s most promising applications is as an alternative to silicon, making ultra-tiny transistors for the supercomputers of the future. Computer processors could run hundreds of times faster by replacing silicon with graphene.
In addition, graphene is almost completely transparent and absorbs only light. It is so dense that even the smallest gas atom (helium atom) cannot penetrate. These features make it ideal for use as a raw material for transparent electronics, such as transparent touch-screen displays, luminous panels, and solar panels. Graphene has been dubbed the “black gold” and the “king of new materials”, with scientists even predicting it will “revolutionize the 21st century”. Set off a disruptive new technological and industrial revolution sweeping the world.
In October 2002, Zhang Bozeng, a Chinese scientist living in the United States, declared the world’s first patent on the composition, production process, and application technology of graphene. In this patent application article, Zhang Bozeng clearly describes the preparation process of single-atom and multi-layer graphene. This is the world’s first patent for monolayer graphene, graphene-reinforced metal matrix, resin matrix, carbon matrix, and ceramic matrix composites. In 2004, Andre Geim and Konstantin Novoselov, physicists at the University of Manchester in the United Kingdom, successfully isolated graphene from graphite, demonstrating that it can exist on its own. They shared the 2010 Nobel Prize in Physics for their work.
With the introduction of the “Made in China 2025” national strategy, support for graphene has increased. The state, local governments, and industrial alliances have supported the development of the graphene industry through various means. “Made in China 2025” graphene industry technology roadmap, has been clear about the industrial development focus, direction, and path, has solved the current preparation technology-related products cost is high, the technology is not mature, the product is not stable, development for a specific occasion more forms and characteristics of the preparation of graphene-based materials and structure control technology. In the future, we will focus on making breakthroughs in graphene preparation technology characterized by large-scale, low-cost, high-quality, uniform, and controllable quality and multi-scale, vigorously developing advanced graphene application technology and downstream product development, and continuously expanding the application field of graphene-related products.
The breakout point of the graphene industry has been formed, and the future will see explosive growth. Graphene has passed its hype phase, and companies have shifted their attention from graphene preparation to application. At present, some companies have the ability to provide graphene, but it is mainly used for experimental and applied research. Few truly realize high-end applications, and the annual production capacity of most relevant companies is less than 100 tons. With the increase of policy support, capital investment, and the breakthrough of macro preparation technology, in the next 5 to 10 years, the annual production capacity of most enterprises will reach thousand tons, and a few large enterprises are expected to reach ten thousand tons.
The graphene market has a broad prospect and is expected to produce huge economic benefits. The world’s major research institutions have predicted the market prospects and scale of graphene. According to the analysis results of various institutions at home and abroad, the next five to ten years will be a period of rapid development for the global graphene industry, and the demand for graphene will continue to increase in all industries. The near-term demand for graphene is mainly from composite materials, concentrated in automotive, plastics, coatings, construction, metals, batteries, aviation, and energy and energy storage. The medium – and long-term demand for graphene is mainly in electronics and photovoltaics and energy storage. With the further development of the graphene industry, its application fields will continue to expand.
