Abstract

The invention discloses a graphene spraying device and a spraying process thereof. The graphene spraying device comprises a box body, wherein a spraying chamber, a feeding device, a recycling device,a powder filtering device and a hot air drying device are arranged in the box body; and graphene powder is sprayed on a PET film or a copper foil in the spraying chamber; and excess graphene powder isrecycled through the recycling device. According to the graphene spraying device and the spraying process thereof, graphene nanoparticles which are lightest, smallest and can float in the air are used as coating materials, a material film is coated with graphene in a spraying mode, so that the production cost is greatly reduced, and the operation is convenient.

Description

technical field [0001] The invention relates to the technical field of graphene automatic spraying, in particular to a graphene spraying device and a spraying process thereof. Background technique [0002] With the shortage of energy resources in the world and the deterioration of the environment, new material technology is more and more widely used in modern life. [0003] 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. [0004] Now, graphene material products are widely used, and one of the graphene heat conduction films with good thermal conductivity is widely used in the technical field of electronic products, and has been well ...
