▎ 摘  要

NOVELTY - The method involves obtaining alkaline graphene oxide solution to adjust the graphene oxide solution to alkaline with a strong base. An appropriate amount of silver nitrate solution is dropped into the amino-terminated hyperbranched polymer solution to be stirred and react. The amino-terminated hyperbranched polymer nanosilver solution is added to the alkaline graphene oxide solution and stirred to obtain graphene oxide/nanosilver composite nanomaterial solution. The graphene oxide/nanosilver composite nanomaterial solution is centrifuged to obtain the composite material, where the supernatant is discarded and tetrahydrofuran is added to disperse into a dispersion. The dispersion liquid is sprayed on the surface of the nonwoven product, and dried to form a composite coating nonwoven material. USE - Method for preparing graphene oxide/nano-silver composite coating non-woven material for disposable protective textiles e.g. masks for use during severe acute respiratory syndrome (SARS) , bird flu, and other viruses. ADVANTAGE - The graphene oxide/nano-silver composite coating non-woven material is efficiently prepared with high quality, by simple method. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic view of a scanning electron microscope (SEM) image of meltblown nonwoven fibers after spray finishing.
