▎ 摘  要

NOVELTY - Preparation of graphite/polypyrrole electromagnetic shielding film comprises mixing graphite oxide and water, ultrasonic dispersing to obtain graphene oxide dispersion, dissolving pyrrole in water-ethanol mixture to get pyrrole solution; adding pyrrole solution in graphene oxide dispersion at ratio of 95:5-70:30, and warming to 90-95 degrees C for 8-24 hours; and cooling mixture to room temperature, adding ferric trichloride, reacting for 4-8 hours, suction filtering to obtain film layer, and drying. USE - Method for preparing graphite/polypyrrole electromagnetic shielding film (claimed). ADVANTAGE - The method increases conductivity of film.
