Description

technical field [0001] The invention belongs to the field of nanometer materials, in particular to a preparation method of graphene nanomaterials. Background technique [0002] Graphene is a carbon atom with sp 2 The hybrid orbitals form a hexagonal two-dimensional carbon nanomaterial with a honeycomb lattice. Graphene has excellent optical, electrical, and mechanical properties, and has important application prospects in materials science, micro-nano processing, energy, biomedicine, and drug delivery, and is considered to be a revolutionary material in the future. Graphene oxide (GO): A layered material obtained by oxidizing graphite. After the bulk graphite is treated with a fuming concentrated acid solution, the graphene layer is oxidized into a hydrophilic graphene oxide, and the interlayer spacing of graphite is changed from that before oxidation to increased to Separated graphene oxide lamellar structures are easily formed by heating or ultrasonic exfoliation in ...
