▎ 摘  要

NOVELTY - A dispersing method of graphene in polyethylene terephthalate (PET) polyester involves (S1) oxidizing quantitative graphene to obtain graphene oxide solution, (S2) adding volatile diamine in the graphene oxide solution for mixing to obtain a mixed solution, (S3) adding polyester monomer into the mixed solution, transferring to a reaction kettle, heating and stirring, and (S4) vacuumizing, stirring at constant temperature, reacting for 1-5 hours, pressurizing and discharging. USE - Dispersing method of graphene in polyethylene terephthalate polyester for use as conductive additive in antistatic or electrostatic dissipative applications. ADVANTAGE - The method is convenient to operate, and provides polyester having low surface resistance and excellent electrostatic dissipation effect. The graphene in the obtained PET polyester has excellent dispersibility and does not agglomerate easily.
