摘要： An intercalation agent for rapid graphite exfoliation in mass production of high-quality graphene is provided, including a transition metal halide salt, a nitrogen source substance and an organic solvent, and the mass ratio of the transition metal halide salt, the nitrogen source substance and the organic solvent is (1-10):1:(2-10). The transition metal halide salt can form a eutectic with the nitrogen source substance or the organic solvent, and the melting point thereof is lower than that of each component, thereby lowering the reaction temperature, and the preparation cost and difficulty; and a hydrogen bond can also be formed between the nitrogen source substance and the organic solvent, thereby avoiding interlayer stacking of the prepared graphene, thus improving the exfoliation efficiency and the product quality.

摘要： A super-flexible high thermal conductive graphene film and a preparation method thereof are provided. The graphene film is obtained from ultra large homogeeous graphene sheets through processes of solution film-forming, chemical reduction, high temperature reduction, high pressure suppression and so on. The graphene film has an intensity in a range of 1.93 to 2.11 g/cm3, is formed by overlapping planar oriented graphene sheets with an average size of more than 100 μm with each other through π-π conjugate action, and comprises 1 to 4 layers of graphene sheets which have few defects. The graphene film can be repeatedly bent for 1200 times or more, with elongation at break of 12-18%, electric conductivity of 8000-10600 S/cm, thermal conductivity of 1800-2600 W/mK, and can be used as a highly flexible thermal conductive device.

摘要： A unitary graphene layer or graphene single crystal containing closely packed and chemically bonded parallel graphene planes having an inter-graphene plane spacing of 0.335 to 0.40 nm and an oxygen content of 0.01% to 10% by weight, which unitary graphene layer or graphene single crystal is obtained from heat-treating a graphene oxide gel at a temperature higher than 100° C., wherein the average mis-orientation angle between two graphene planes is less than 10 degrees, more typically less than 5 degrees. The molecules in the graphene oxide gel, upon drying and heat-treating, are chemically interconnected and integrated into a unitary graphene entity containing no discrete graphite flake or graphene platelet. This graphene monolith exhibits a combination of exceptional thermal conductivity, electrical conductivity, mechanical strength, surface smoothness, surface hardness, and scratch resistance unmatched by any thin-film material of comparable thickness range.
