Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of carbon materials, and in particular relates to a device for preparing graphene capacitors. [0003] 【Background technique】 [0004] Due to its unique structure and photoelectric properties, graphene has become a research hotspot in the fields of carbon materials, nanotechnology, condensed matter physics and functional materials. Graphene is a new type of nanomaterial with the thinnest, highest strength, and strongest electrical and thermal conductivity found so far. Graphene is called "black gold" and is the "king of new materials". Its theoretical specific surface area is as high as 2630m2 / g. It can be used in effect transistors, electrode materials, composite materials, liquid crystal display materials, sensors, etc. [0005] In a narrow sense, graphene refers to single-layer graphite with a thickness of 0.335nm and only one layer of carbon atoms, but in fact, graphite structures within 10 laye...
