Description

technical field [0001] The invention belongs to the technical field of graphene oxide preparation, in particular to a graphene oxide preparation reaction kettle. Background technique [0002] Graphene oxide flakes are the product of graphite powder after chemical oxidation and exfoliation. Graphene oxide is a single atomic layer that can expand to tens of microns in the lateral dimension at any time. Graphene oxide is generally oxidized with potassium permanganate in concentrated sulfuric acid and graphite powder to obtain brown graphite flakes with derivatized carboxylic acid groups on the edges and mainly phenolic hydroxyl groups and epoxy groups on the plane. Graphite flakes can be exfoliated into graphene oxide by ultrasonic or high-shear vigorous stirring, and a stable, light brown single-layer graphene oxide suspension is formed in water; graphene oxide can be obtained after drying; In the graphene process, a magnetic stirrer is generally used for stirring, but the pr...
