The invention discloses a screening device for graphene purification and a use method. The screening device comprises a screening barrel, material leaking holes are formed in the surface of the screening barrel, the right side of the screening barrel communicates with a feeding pipe, the left side of the screening barrel communicates with a discharging pipe, the surface of the feeding pipe and thesurface of the discharging pipe are both sleeved with bearing seats, first connecting rods are fixedly connected to the top of the bearing seats, a second connecting rod is fixedly connected to the tops of the first connecting rods, third connecting rods are fixedly connected to the two ends of the second connecting rod, and a motor is fixedly connected to the right side of the third connecting rod on the left side. The screening device has the advantages of being capable of conducting multiple screening on graphene, high in screening efficiency and high in applicability, and the problems that an existing graphene screening device screens the graphene only through a single screening plate, cannot conduct multiple screening on the graphene, is low in screening efficiency, reduces the applicability of the screening device and is inconvenient for people to use are solved.
Description
Technical field [0001] The invention relates to the technical field of graphene sieving, in particular to a sieving device for graphene purification and a use method. Background technique [0002] Graphene is a two-dimensional carbon nanomaterial with a hexagonal honeycomb lattice composed of carbon atoms and sp2 hybrid orbitals. Graphene has excellent optical, electrical, and mechanical properties. It is used in materials science, micro-nano processing, energy, and biology. It has important application prospects in medicine and drug delivery. It is considered to be a revolutionary material in the future. The common powder production methods of graphene are mechanical peeling method, redox method, SiC epitaxial growth method, and film production method is Chemical vapor deposition method. [0003] Graphene needs to be sieved during the purification process. The existing graphene sieving device only screens graphene through a single sieving plate, and cannot perform multiple sievin...
