AI Technical Summary
Technical Problem
The existing technology addresses the problem of small graphene coating area and low quality in graphene-metal composite materials.
Method used
The process involves pre-preparing metal raw materials into liquid or powder form, spraying them into a first reaction zone to prepare solid powder, then heating them in a second reaction zone until part or all of the surface is in a liquid state to deposit graphene, and finally cooling them in a cooling zone to form a high-quality, large-area graphene coating layer.
Benefits of technology
This improved the quality and coverage area of graphene-metal composite materials, reduced costs, and increased production efficiency.
