Description

Technical Field

[0001] The utility model relates to the technical field of graphene water washing, in particular to a high-efficiency water washing device for graphene production. Background Art

[0002] Graphene is a two-dimensional carbon nanomaterial composed of hexagonal honeycomb lattices composed of sp2 hybrid orbitals of carbon atoms. Graphene has excellent optical, mechanical and electrical properties, and has very broad application prospects in materials science, nanoprocessing and biomedicine. It is considered to be a revolutionary material of the future.

[0003] The existing preparation of graphene usually grows graphene on a metal substrate and then removes the metal substrate to obtain the graphene. When removing the metal substrate, it is generally removed by acid immersion, so a small amount of acid will remain on the surface of the graphene after removing the substrate, which needs to be cleaned and dried using a graphene production water washing device.

[0004] However, some of the existing water-washing devices for graphene production have a lot of residual moisture on the surface of the graphene after water washing, which easily leads to unsatisfactory air-drying effect and inconvenience in use. At the same time, the vapor of acidic substances produced lacks treatment, which not only pollutes the atmospheric environment, but also seriously endangers the health of workers. Moreover, most of the existing water-washing devices for graphene production are single-sided cleaning, with poor cleaning effect and easy acid residue. Utility Model Content
