Electrospun Polyamide 6 Bead-on-String Fiber with Gradient Structure/Nanofiber Membranes for Effective Air Filtration
摘要
Abstract
The double-spraying electrospinning method was employed to prepare polyamide 6 (PA6) bead-on-string fiber/nanofiber membranes .The influence of the mass fraction of PA 6 bead-on-string fiber solution and the mass ratio of bead-on-string fiber/nanofiber solution on morphology and air filtration performance of the membranes was investigated .The filtration mechanism was analyzed . Finally , the gradient-structured bead-on-string/nanofiber filtration material with high-efficiency and low-resistance was developed . Results show that the bead-on-string fiber/nanofiber membrane exhibits the highest quality factor when the PA 6 mass fractions are 10％ and 18％ used to fabricate bead-on-string fiber and nanofiber ,respectively ,and the mass ratio of the bead-on-string fiber/nanofiber solution is 3/7 . Adding moderate bead-on-string fibers in nanofibers can make the membrane fluffy and form tortuous micropores .Therefore ,the resistance is reduced and the filtration efficiency keeps stable .By controlling the mass ratio of the bead-on-string fiber/nanofiber solution at 2/8 ,3/7 and 4/6 sequentially ,the gradient-structured bead-on-string fiber/nanofiber material can be prepared with the filtration efficiency of 99 .1％ and resistance pressure drop of 116 Pa.关键词
