Description

technical field [0001] The invention belongs to the technical field of graphene preparation devices, in particular to a preparation device for highly dispersed graphene powder. Background technique [0002] Graphene is a single layer of carbon atoms connected by sp2 hybrid orbitals to form a hexagonal honeycomb lattice. It has anomalous quantum Hall effect, bipolar electric field effect, and high carrier concentration (2×106cm2V-1s-1 ), high thermal conductivity (5000WmK-1) and high specific surface area (2630m2g-1), it is considered to be one of the most potential two-dimensional materials. However, single-layer graphene is a non-gap material, which limits its wide application in various applications such as microelectronics. Therefore, researchers have developed various means to tune the electronic structure of graphene, including surface modification and chemical doping. After doping with heteroatoms such as nitrogen, sulfur, phosphorus, and boron, the physical and chem...
