▎ 摘　　要

NOVELTY - Preparation of inkjet ink involves adding catalyst-containing tetrahydrofuran solution to graphene oxide solution, heating and then stirring, adding hyperbranched silane monomer, heating, refluxing to obtain hyperbranched polysilane-modified graphene oxide, mixing dicyclopentadiene-type cyanate and pigment, adding hyperbranched polysilane-modified graphene oxide, heating and then prepolymerizing to obtain modified graphene oxide composite pigment, mixing the modified graphene oxide composite pigment, solvent, water-soluble polymer, viscosity modifier and pH regulator to obtain hyperbranched polysilane-modified graphene oxide ink and filtering the hyperbranched polysilane-modified graphene oxide ink using graphite oxide alkenyl polyethersulfone nanofiltration membrane. USE - The method is useful for preparation of inkjet ink.
