Description

Technical Field

[0001] The utility model belongs to the technical field of instrument processing, and particularly relates to an oxidation device for modifying power tube plastic particles with graphene oxide stock solution. Background Technique

[0002] The solution mixing method of modifying plastics with graphene oxide stock solution is an important method for preparing graphene / polymer composites at present. It is to immerse the plastic particle matrix in the graphene oxide stock solution, and the immersed plastic particles are dried to obtain graphene-modified plastic particles.
