Abstract

The invention provides a complete device of preparing graphene by a jet flow. A graphite raw material and a medium solution are intensively mixed, primarily stripped and mixed by a high-mixing stirrer, and accelerated by an acceleration pump to enter a spray drying chamber from a jet nozzle; the materials are collided and stripped in the jet nozzle and ejected to enter the spray drying chamber; the solution is evaporated at the high temperature in the drying chamber; a graphene material is obtained; and finally, a collection mechanism collects the graphene. According to a method, the stripping and dispersion of the graphene are achieved in a one-stop manner; the stripping efficiency of the graphene is improved; a structure of the graphene is kept better, so that the high-quality graphene is obtained; at the same time, the problem of poor dispersity of the graphene is solved; and continuous and mass production of the graphene is promoted.

Description

technical field [0001] The invention relates to the field of nanomaterial preparation devices, in particular to a complete device and method for preparing graphene by using jet flow. Background technique [0002] In 2004, two scientists from the University of Manchester in the United Kingdom discovered graphene using the method of micromechanical exfoliation, and won the Nobel Prize in Physics in 2010. Graphene is a flat plate structure with a single atom thickness and sp2 bonded carbon atoms. In theory, it has a perfect hexagonal network structure and exhibits excellent electronic stability, thermal conductivity, optical properties, and mechanical properties. Since the discovery of graphene, due to its excellent performance and huge market application prospects, it has triggered a research boom in the fields of physics and material science. In graphene, each carbon atom has an unbonded p-electron. These p-electrons can move freely in the crystal, and the movement speed is ...
