▎ 摘  要

NOVELTY - Graphene containing dental floss comprises 90-99 wt.% polytetrafluoroethylene, 0.01-8 wt.% graphene, 0.01-9 wt.% polyvinylpyrrolidone and 0.01-7 wt.% liquid paraffin. USE - Used as graphene containing dental floss. ADVANTAGE - The dental floss: has excellent antibacterial and antiinflammatory effects and excellent biocompatibility, high mechanical strength and low cost; solves the problems of single function of dental floss; is easy to produce medicine resistance when added with medicine; and is convenient for use. DETAILED DESCRIPTION - AN INDEPENDENT CLAIM is also included for preparing graphene containing dental floss. The method utilizes ethanol solution.
