摘要

采用静电纺丝技术制备聚丙烯腈(PAN)/聚乙烯吡咯烷酮(PVP)纳米纤维,将其包覆在水刺粘胶非织造布表面,制备了PAN-PVP纳米纤维/水刺粘胶非织造复合材料,考察了PAN与PVP质量比对PAN/PVP纳米纤维形貌的影响,并对复合材料的过滤性能、比表面积、透气性等进行了研究。结果表明:纺丝液中PAN和PVP最佳质量比为7:3,静电纺丝时间为2h制备的复合材料对空气中粒径大于2μm颗粒物的过滤效率达99.93%;压差为200Pa时,复合材料的透气率为210.83mm/s,与普通口罩透气率相当;与水刺粘胶非织造布相比,复合材料的比表面积增大,过滤性能明显提高。

Abstract

Polyacrylonitrile(PAN)/polyvinylpyrrolidone(PVP) nanofibers were made by electrospinning technology,the nanofibers were collected on the surface of the viscose spunlaced nonwovens to prepare PAN-PVP nanofiber/viscose spunlace nonwoven composite.The influence of mass ratio of PAN and PVP on the PAN/PVP nanofiber's morphology was investigated,and the filtration performance,specific surface area,and permeability of the composite materials were studied.The experimental results showed that the optimal mass ratio of PAN and PVP was obtained to be 7:3.The composite material with electrospinning time of 2h had a air filtration efficiency of 99.93% for particles with diameter over 2μm.And its permeability was 210.83mm/s under the given pressure(200Pa),which was equivalent to the air permeability of normal masks.Compared with the viscose spunlaced nonwovens,the specific surface area of the composite material increased and the filtration performance was significantly improved.
