▎ 摘 要
NOVELTY - Degradable nanofiber mask comprises a filter core composed of 10-20 pts. wt. graphene oxide, 2-5 pts. wt. photocatalytic nanoparticles and 80-200 pts. wt. polylactic acid, where the photocatalytic nanoparticles are partially embedded in the graphene oxide interlayer structure. USE - Used as degradable nanofiber mask. ADVANTAGE - The nanofiber mask: has good tensile strength; and has excellent strength and no internal structure damage even after repeated rubbing to simulate real usage condition.
