▎ 摘  要

NOVELTY - Preparing anti-fog polylactic acid nanofiber membrane involves modifying graphene in mixed acid and washing to obtain modified graphene. The obtained modified graphene is added to polylactic acid uniform solution, and then the coupling agent is added, and the modified polylactic acid solution is uniformly obtained by stirring. The obtained modified polylactic acid solution is spun by the electrospinning device. The membrane and the fiber membrane are dried in a vacuum oven to obtain a nanofiber membrane. USE - Method for preparing anti-fog polylactic acid nanofiber membrane. ADVANTAGE - The method enables to preparing anti-fog polylactic acid nanofiber membrane which is ultimately produces coupling between filler and two components of polylactic acid, and improves physical and mechanical properties of the blend.
