| 摘 要： | 为开发高效低阻的空气过滤材料，采用静电纺丝技术制备了聚偏氟乙烯（PVDF）-聚丙烯腈（PAN）复合纳米纤维，并与聚丙烯熔喷非织造布复合制得高效复合过滤材料，研究了PVDF与PAN的质量比对溶液性质、表面形貌、比表面积、透气性和过滤性能的影响。结果表明，当PVDF与PAN质量比为3：5时，其溶液可纺性最好，所得纤维直径均匀，约为0.59 μm；利用BET比表面积分析仪测试可得其比表面积约为PVDF与PAN质量比为2：1时的两倍；利用滤料测试仪对PVDF-PAN/熔喷聚丙烯（PP）无纺布复合滤材的过滤性能进行测试，结果表明，静电纺PVDF-PAN纳米纤维层可显著提高聚丙烯熔喷非织造布的过滤性能，PVDF-PAN/熔喷PP无纺布过滤效率可达99.95%，明显高于熔喷无纺布的过滤效率（65%），过滤阻力为77 mmH2O（1 mmH2O=9.8 Pa），过滤品质因子达0.0987，远高于熔喷无纺布的过滤品质因子0.0168，过滤效果得到显著提升。

| Abstract: | The high filtration efficiency and low flow resistance of air filtration materials were successfully prepared by composing electrospinning poly(vinylidene fluoride) (PVDF)-polyacrylonitrile (PAN) nanofibers with polypropylene(PP) melt-blown nonwoven. The influence of the PVDF to PAN mass ratio on the solution properties, morphology, specific surface area and filtration properties were investigated. The results show that when the PVDF to PAN mass ratio is 3:5, the solution has excellent spinnability and the well-distributed nanofibers with mean diameter of 0.59 μm can be formed. BET test result shows that it goes for nearly double the specific surface area when PVDF to PAN mass ratio decreases from 2:1 to 3:5. Besides, the filtration efficient and resistance determined by TSI 8130 filter were tested. Results reveal that electrospinning PVDF-PAN nanofibers can significantly improve the filtration performance of polypropylene melt-blown nonwovens, the filtration efficiency of PVDF-PAN/melt-blown PP nonwoven reaches to 99.95%, significantly higher than that of melt-blown nonwoven with 65%, the filtration resistance is 77 mm H2O (1 mm H2O=9.8 Pa), the filter quality factor reaches 0.0987, which is more higher than 0.0168 of melt-blow nonwoven. The filtration properties significantly enhance by composing electrosping PVDF-PAN nanofiber with melt-blow nonwoven. |
