摘要
通过静电纺丝制备的聚乙烯醇(PVA)基纳米纤维膜具有多孔结构、高比表面积、形貌可控和可生物降解等特点,在空气过滤领域具有广阔的应用前景.首先介绍了静电纺丝技术以及纳米纤维空气过滤机理,随后着重总结了PVA与纳米粒子、壳聚糖、环糊精以及单宁酸共同制备静电纺丝纳米纤维膜在空气过滤领域的研究进展,最后对未来发展进行了展望.
Abstract
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.
