  2. Graphene is a honeycomb planar film formed by sp2 hybridization of carbon atoms. It is a quasi-two-dimensional material with only one atomic layer thickness, so it is also called monatomic layer graphite.  延时符

  4. Graphene King of new materials “ MostThin “ “ Black gold Maximum Intensity “ “ Most Conductive Conductivity “ “ “ Change the 21st Century

  5. Physical Properties Strength and Flexibility Tensile strength 1 125GPa Young's modulus 3 42 N/m2 Elastic modulus 2 1.1TPa Graphene with 1m2 withstand 4kg 4 100 times

  6. Physical Properties Conductive Thermal Conductivity The carrier properties of graphene derivatives has great potential for further development of graphene-based electronic and energy devices Unique Carrier Properties Quality of the Dirac fermions The Fermi wavelength in high-quality bulk graphene can be tuned up to hundreds of nanometres.

  7. Chemical Properties Oxidation Graphene can react with active metals, or oxidized in air. Reducibility It can be oxidized by oxidizing acid, by which the graphene can be cut into small pieces. Aromaticity Graphene is aromatic and has aromatic properties. Other Properties Adsorpt and desorpt of various atoms and molecules, with super-hydrophobic and super-oleophilic

  8. Chemical Properties Stability The structure of graphene is very stable, carbon-carbon bond is only 1.42. The connection between the carbon atoms inside the graphene is very flexible. When the external force is applied to the graphene, the carbon atoms are bent and deformed, so that the carbon atoms need not be rearranged to accommodate the external forces, thus maintaining the structural stability. In addition, when the electrons in the graphene move in the track, they do not scatter due to lattice defects or the introduction of foreign atoms. As the interatomic force is very strong, at room temperature, even if the surrounding carbon atoms crashed, the internal interference of graphene is very small.  延时符
