▎ 摘　　要

NOVELTY - A graphene waterproof antistatic coating is prepared by heating and dissolving granular polyvinyl alcohol in deionized water, adding trifunctional aziridine crosslinking agent, stirring and fully reacting, adding sodium carboxymethyl cellulose, heating and stirring to dissolve until solution is clear and transparent, adding graphene slurry and sodium hydroxide, slightly stirring and putting into ultrasonic machine for ultrasonic to obtain graphene dispersion liquid, coating on different substrates (PET, polyimide and glass plate) by casting method and naturally drying to obtain graphene antistatic coating coated on substrate. USE - The method is used for preparing graphene waterproof antistatic coating used for various substrates. ADVANTAGE - The method is environment-friendly and relatively simple in process, has low production cost, does not need to process more than graphene, and obtains series of graphene antistatic film with different properties by adjusting dosage of adding substance.
