▎ 摘  要

NOVELTY - Preparation of high performance functionalized graphene composite porous nano antibacterial fiber comprises dissolving acrylonitrile-vinylidene chloride copolymer in dimethylformamide and acetone solution, mixing on 1-1000 revolutions per minute, freeze drying antibacterial powder at 0-100 degrees C for 3-72 hours, drying, mixing dimethylformamide and acetone solution for 2-72 hours, mixing on 1-1000 revolutions per minute, dispersing functionalized graphene dispersion as cortex layer, using acrylonitrile-vinylidene chloride copolymer as core layer, metering, spinning and spraying. USE - Method of preparing high performance functionalized graphene composite porous nano antibacterial fiber (claimed). ADVANTAGE - The method increases specific surface area of the fiber, increases antibacterial activity, has 87% antibacterial rate of Staphylococcus aureus and 83% antibacterial rate of Escherichia coli, simple, easy to implement, can be recycled and saves cost. DETAILED DESCRIPTION - Preparation of high performance functionalized graphene composite porous nano antibacterial fiber comprises dissolving 100 pts. wt. acrylonitrile-vinylidene chloride copolymer in 100-1000 pts. wt. dimethylformamide and acetone solution for 2-72 hours, mixing on 1-1000 revolutions per minute, freeze drying antibacterial powder at 0--100 degrees C for 3-72 hours, drying, mixing 100-1000 pts. wt. dimethylformamide and acetone solution for 2-72 hours, mixing on 1-1000 revolutions per minute, dispersing functionalized graphene dispersion as cortex layer, using acrylonitrile-vinylidene chloride copolymer as core layer, metering, spinning and spraying.
