Description

Technical field

[0001] The present invention relates to a flotation method of a method of preparing an uniform crystalline graphene, belonging to the field of graphene. Background technique

[0002] Graphene is a SP 2 Hybrid connection carbon atoms are closely stacked into the thinnest, most hard nanomaterials of single-layer two-dimensional honeycomb lattice structure, and it is almost completely transparent, only 2.3% of light, carbon atoms in graphene The force is very strong, at normal temperature, even if the surrounding carbon atom is crushed, the interference of the inner electrons in the graphene electron is also very small, and the electron mobility is over 15,000 cm2 / v · S, and the motor speed of the electron movement is 1 / 300, also carbon-bit nanotubes or silicon crystals, and only about 10 6 Ω · cm of resistivity, lower than copper and silver. Therefore, graphene has excellent optical, electrical, mechanical properties, and important application prospects in mater...
