▎ 摘　　要

NOVELTY - Preparing graphene oxide/aramid fiber/graphene oxide composite film, comprises (a) adding Kevlar(Light strong para-aramid synthetic fiber) wire and potassium hydroxide solid into dimethyl sulfoxide solvent, stirring to obtain dark red aramid fiber nanofiber solution; (b) placing graphene oxide in dimethyl sulfoxide solvent, ultrasonically dispersing to obtain graphene oxide dispersion; (c) adding deionized water into graphene oxide dispersion, filtering graphene oxide dispersion to obtain pure graphene oxide film; (d) adding aramid fiber nanofiber solution into graphene oxide dispersion, configuring aramid fiber nanofiber solution in graphene oxide dispersion to be a mixed solution of 5-80 wt.%, adding deionized water for ultrasonic treatment to obtain mixed dispersion liquid of graphene oxide and aramid fiber; and (e) filtering mixed dispersion into a film, placing film in fume hood overnight to obtain graphene oxide/aramid fiber/graphene oxide composite film peeled off and drying. USE - The method is useful for preparing graphene oxide/aramid fiber/graphene oxide composite film. ADVANTAGE - The oxidation graphene/aramid fiber graphene composite film has very good mechanical stability and water stability.
