摘要
采用静电纺丝技术,以不同质量分数的石墨烯为增强剂,制备了不同实验参数的聚丙烯腈/石墨烯复合纳米纤维膜,观察并分析了它们的微观结构、透气性能和过滤性能,发现当石墨烯质量分数为1.0%、纺丝时间为30 min时,制备的聚丙烯腈/石墨烯复合纳米纤维膜过滤性能最优,此时纳米纤维膜的透气率达到144 mm/s,过滤效率为95.01%,阻力压降为60.76 Pa,品质因子达到较高值0.04934 Pa^(-1)。
In this paper,PAN/Gr composite nanofiber membranes with different Gr fractions and different experiment parameters were prepared by electrospinning technology and graphene as the reinforcing agent.Their microstructure,permeability and filtration properties were observed and analyzed.The results showed that when the mass fraction of Gr was 1.0%and the spinning time was 30 min,the filtration performance of PAN/Gr composite nanofiber membrane was the best.Meantime,the permeability of the nanofiber membrane reaches the maximum of 144 mm/s,the filtration efficiency is 95.01%,the resistance pressure drop is 60.76 Pa,and the quality factor reaches 0.04934 Pa^(-1).The research content lays a certain theoretical foundation for enriching the options of air purification materials.
