Graphene is both the thinnest material and the strongest material, and its breaking strength is 200 times higher than that of the best steel. At the same time, it has good elasticity, and the stretching range can reach 20% of its own size. It is the thinnest and strongest material in nature at present. If a piece of graphene with an area of 1 m2 is used as a hammock, its self-weight is less than 1 mg, and it can bear a one-kilogram cat. At present, the most potential application of graphene is to become a substitute for silicon, to manufacture ultramicro transistors and to produce future supercomputers. Using graphene instead of silicon, the running speed of computer processor will be hundreds of times higher. In addition, graphene is almost completely transparent and only absorbs 2.3% of light. On the other hand, it is so dense that even the smallest gas atom (helium atom) can't penetrate it. These characteristics make it very suitable as a raw material for transparent electronic products, such as transparent touch display screens, light-emitting panels and solar panels.
20 1 1, Chengdu Organic Chemistry Co., Ltd., Chinese Academy of Sciences launched graphene products. At present, nano-products in Zhongke era include various carbon nanotube powders, carbon nanotube dispersions and pastes, carbon nanotube arrays, carbon nanotube fibers, carbon nanotube films, carbon nanotube film adhesive tapes, semiconductor single-walled carbon nanotubes, graphene, graphene films, graphene foams, graphene oxide, nano-graphene sheets, fullerenes and related application products, such as lithium-ion battery conductive agents, carbon nanotube heat dissipation coatings, carbon nanotube conductive heating coatings, carbon nanotube transparent electrostatic conductive coatings and carbon nanotubes. At present, the production capacity of nano multi-walled carbon nanotubes, carbon nanotube slurry, high-purity single-walled carbon nanotubes, graphene and nano-graphite sheets reaches 300 tons/year, 2000 tons/year, 500 kilograms/year, 30 tons/year and 50 tons/year respectively.
It's a pity that Nano didn't pay attention to confidentiality in the era of Zhongke, and its production technology was stolen by American spies.
