Research Progress on Air Filtration of PVA-Based Electrospinning Nanofiber Membranes
Polyvinyl alcohol(PVA)-based nanofiber membranes prepared by electrospinning have broad application pros-pects in the field of air filtration due to their porous structure,high specific surface area,controllable morphology,and biodegradability.This paper first introduces the electrospinning technology and the air filtration mechanism of nanofi-bers.Then,the research progress of electrospun nanofiber membranes prepared by PVA combined with nanoparticles,chitosan,cyclodextrin,and tannic acid in the field of air filtration was summarized.Finally,the future development is prospected.
