Description

Technical Field

[0001] The utility model relates to the technical field of graphene material production, in particular to a raw material reaction device for graphene material production. Background Art

[0002] Graphene is a carbon atom in the form of sp 2 The two-dimensional carbon nanomaterial with hybrid orbitals forming a hexagonal honeycomb lattice has excellent optical, electrical and mechanical properties. It has important application prospects in materials science, micro-nano processing, energy, biomedicine and drug delivery, and is considered to be a revolutionary material of the future.

[0003] The production of graphene materials is currently the most difficult problem that needs to be overcome. One of the methods that may achieve large-scale production of graphene powder is to use a method combining the Hummers method with solution reduction: first, graphite is subjected to temperature-controlled intercalation oxidation treatment to obtain graphite oxide, and then ultrasonic exfoliation is performed to obtain graphene oxide, which is then reduced with reducing agents such as hydrazine hydrate and sodium borohydride to obtain graphene. During the production reaction, the mixed raw materials need to be temperature monitored to prevent the internal temperature from being unfavorable for the production of graphene materials. The existing raw material reaction device uses heating plates and cooling plates to regulate the temperature inside the device. The heating plates and cooling plates will make the temperature near the heating plates and cooling plates inconsistent with the temperature far away from them, resulting in local temperatures that are too high or too low, affecting the quality of graphene material production.
