NOVELTY - Preparation of composite fabric involves ultrasonically dissolving 0.3-0.8 mg/mL graphene oxide in ultrapure water, adding 8-15 mg/mL polyethyleneimine solution to blend, adjusting the pH to 6-10, adding 1-ethyl-3-(3-dimethylaminopropyl)-carbodiimide hydrochloric acid catalyst, stirring for 20-30 hours to get graphene oxide-polyethyleneimine dispersion, freeze drying to obtain graphene oxide-polyethyleneimine powder, adding 0.2-0.5 m/mL aqueous solution of graphene oxide-polyethyleneimine powder, adding norfloxacin (NFX), ultrasonically dispersing, adjusting the pH to 3-5, magnetically stirring to get the reaction solution, freeze drying to obtain graphene oxide-polyethyleneimine-norfloxacin (GO-PEI-NFX) composite material powder in a ratio of 1:5, preparing nano-fiber yarn containing the graphene oxide-polyethyleneimine-norfloxacin composite powder and weaving to weave the nanofiber yarn into a nanofiber fabric. USE - Preparation of composite fabric (claimed). ADVANTAGE - The prepared composite fabric provides graphene oxide as a carrier for nanocomposites, which can be loaded with drugs to exert its antibacterial properties, grafting polyethyleneimine on the surface of graphene oxide effectively avoids the material aggregation and precipitation in aqueous solution. The graphene composite material and the spinning polymer aggregated into yarns using electrostatic spinning technology, which gives nano yarns with excellent antibacterial properties, and then woven into antibacterial fabrics.
