The invention discloses a preparation method of graphene oxide/silicon dioxide/high molecular polymer composite nanofiltration membrane. The specific steps include: preparing graphene oxide/silica composite; Dissolve in solvent to prepare spinning solution; prepare graphene oxide/silica/polymer composite nanomembrane filter layer material; prepare non-woven fabric/graphene oxide/silica/polymer composite nanometer Membrane filter material; and then dried to obtain graphene oxide/silicon dioxide/high molecular polymer composite nanofiltration membrane. The preparation method of graphene oxide/silicon dioxide/high molecular polymer composite nanofiltration membrane of the present invention, the graphene oxide/silica/high molecular polymer composite nanofiltration membrane prepared by the preparation method has good filtration properties , adsorption effect, with anti-PM2.5 haze, release negative ions, low temperature far-infrared, antibacterial, antibacterial, anti-ultraviolet and other functions. |
