▎ 摘 要
NOVELTY - Functionalized graphene / polyaniline composite filter membrane comprises a matrix, functionalized graphene oxide, and polyaniline grafted on the film surface. USE - Functionalized graphene / polyaniline composite filter membrane. ADVANTAGE - The functionalized graphene / polyaniline composite filter membrane has simple preparation process, low cost, and good purification effect. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing functionalized graphene / polyaniline composite filter membrane, which comprises preparing functionalized graphene oxide into a film, and then immersing it into a mixed acid solution of aniline and ammonium persulfate, after reacting for a certain time, taking out and cleaning the surface polyaniline to obtain a functionalized graphene oxide / polyaniline composite filter membrane.
