Graphene is carbon atoms tightly packed into a single two-dimensional honeycomb lattice structure of a kind of carbon material, nanometer material is the most thin so far known thickness is only 0.335 nm, is only one-200000th of a human hair, is to build other dimension carbonaceous materials (such as zero dimension of fullerenes, one-dimensional nanotubes, three-dimensional graphite) of the basic unit, Graphene has a theoretical specific surface area of up to 2630 m2 /g, thermal conductivity of up to 5300 W/mK, and carrier mobility of 200,000 cm2 /Vs at room temperature.
Huasheng Graphite Co., Ltd. has cooperated with Shanghai Jiao Tong University to develop the chemical preparation technology of large-size graphene, and at the same time, the company has independently developed the physical preparation technology of nano-size graphene. The company has one REDOX graphene production line and one arc graphene production line.
Arc graphene powder is a nanoscale graphene product prepared by our company using the leading arc plasma discharge technology. The product has the advantages of high purity, high conductivity and zero oxygen content, etc. It is a high-quality raw material for conductive paste, conductive ink and other products. It has a wide range of applications in batteries, supercapacitors, conductive composites and so on. According to the range of lamellar thickness, there are three types of arc graphene powders: AD-1, AD-2 and AD-3.
