▎ 摘  要

NOVELTY - Preparation of graphene/polyethyleneimine gas barrier composite membrane involves dripping graphene oxide dispersion liquid in polyethyleneimine solution, reacting at 85-95 degrees C for 12-24 hours, obtaining mixed liquid with mass ratio of graphene oxide and polyethyleneimine of 1:(1-9), suction-filtering and drying. USE - Preparation of graphene/polyethyleneimine gas barrier composite membrane (claimed). ADVANTAGE - The method enables preparation of graphene/polyethyleneimine gas barrier composite membrane having excellent barrier performance, by improving dispersion uniformity of graphene oxide layer in base component.
