▎ 摘　　要

NOVELTY - Preparing doped graphene oxide/nano silver melt-blown non-woven material, comprises (i) adjusting the pH value of the graphene oxide solution to alkaline with a strong base, (ii) adding amino-terminated hyperbranched polymer solution into the alkaline graphene oxide solution, and uniformly ultrasonically mixing at room temperature to obtain amino-terminated hyperbranched polymer-modified graphene oxide solution, (iii) adding silver nitrate solution into the amino-terminated hyperbranched polymer-modified graphene oxide solution, stirring and centrifuging to remove the supernatant to obtain modified material, and uniformly dispersing the modified material in tetrahydrofuran to obtain dispersion, (iv) spraying the dispersion into the masterbatch, stirring, and drying to obtain spinning masterbatch doped with modified graphene oxide, and (v) forming the spinning masterbatch. USE - The method is useful for preparing doped graphene oxide/nano silver melt-blown non-woven material. ADVANTAGE - The non-woven material has improved and stable disinfection ability of viruses and bacteria.
