[0002] A graphene plate is a new type of functional material formed by compounding graphene with a single-layer carbon atom structure and traditional substrates (such as wood boards, plastics, etc.) through nanotechnology. Graphene is a two-dimensional honeycomb lattice material composed of carbon atoms with sp 2 hybrid orbitals, having high strength (the strength is 100 times that of steel), high flexibility (can be stretched to 120% of its own size), excellent electrical conductivity (the electron mobility reaches 15000 cm 2 / Vs, and the resistivity is only 10 6 Ω·cm), and thermal conductivity (the thermal conductivity is 5300 W / m·K), as well as high light transmittance (the light transmittance is 97.4%). By uniformly dispersing graphene, the board retains its antibacterial (the antibacterial rate exceeds 99%), light weight and high strength (the density is only 1 / 3 of solid wood, and the flexural strength reaches 50 - 80 MPa), environmental protection and long-lasting (the outdoor life reaches 20 years) and other characteristics, while being compatible with traditional processing technologies.
