| 摘 要： | 为制备高过滤效率、低过滤阻力的空气过滤材料,将氧化石墨烯纳米颗粒(GO)掺杂到聚酰亚胺(PI)纺丝溶液中,制备氧化石墨烯/聚酰亚胺(GO/PI)复合纳米纤维过滤材料。通过观察其形貌、过滤性能来确定最优纺丝工艺参数。结果表明:当PI质量分数为30%,GO质量分数为1%,纺丝电压为25 kV,接收距离为20 cm时,复合纳米薄膜的纤维形貌较好,过滤性能优良。与PI纯组分纳米纤维过滤材料相比,GO/PI复合纳米纤维过滤材料的过滤性能更好,制得GO/PI复合纳米纤维膜的平均孔径为1.8μm,过滤效率为99.68%,过滤阻力仅为85.35 Pa。

| Abstract: | In order to prepare air filtration materials with high filtration efficiency and low filtration resistance,graphene oxide nanoparticles are doped into polyimide(PI)spinning solution to prepare graphene oxide/polyimide(GO/PI)composite nanofiber filtration materials.The optimum spinning parameters are determined by observing the nanofier morphology and test filtration performance.The results show that when PI concentration is 30%,GO concentration is 1%,spinning voltage is 25 kV,and receiving distance is 20 cm,composite nanofiber film fiber has the best morphology and excellent filtration performance.Compared with pure component PI nanofiber filtration materials,GO/PI composite nanofiber filtration materials have better filtration performance.The average pore diameter of GO/PI composite nanofiber membrane is 1.8μm,the filtration efficiency is 99.68%,and the filtration resistance is only 85.35 Pa. |
