Due to its small diameter and high density, electrospun nanofiber membranes have high resistance which obstacles their application. In this paper, we proposed a new electrospinning method based on low-temperature, which can affect the deposition process of electrospinning by utilizing the freezing process of steam in the receiving plate. The filling and supporting of ice could enlarge the pores of membranes and intervals among fibers, which caused the high porosity (92 %), rough surface, fluffy structure and low pressure drop (123 Pa) of polyvinylidene fluoride (PVDF) nanofibrous membranes. The results suggested that the electrospinning method is a promising way to prepare nanofibrous membranes with high air permeability and fluffy structure for air filtration.

基于低温静电纺丝技术的高透气性和蓬松结构的纳米纤维膜

由于其细小直径和高密度,电纺纳米纤维膜具有高电阻,这阻碍了其应用。在本文中,我们提出了一种基于低温的新型静电纺丝方法,该方法可以利用接收板中蒸汽的冻结过程来影响静电纺丝的沉积过程。冰的填充和支撑会扩大膜的孔和纤维之间的间隔,从而导致聚偏二氟乙烯(PVDF)纳米纤维膜的高孔隙率(92%),表面粗糙,蓬松的结构和低压降(123 Pa)。结果表明,静电纺丝法是制备具有高透气性和蓬松结构的纳米纤维膜用于空气过滤的一种有前途的方法。
