摘要
将石墨烯(GR)纳米颗粒掺杂到聚丙烯腈(PAN)纺丝溶液中,利用静电纺丝技术制备石墨烯/聚丙烯腈(GR/PAN)复合纳米纤维膜。研究PAN质量分数、GR用量、纺丝电压及接收距离对GR/PAN复合纳米纤维膜形貌和过滤性能的影响,发现最优纺丝工艺参数为PAN质量分数14.0%、GR用量1.5%、纺丝电压26 kV、接收距离14 cm、注射速度1 mL/h。此最优纺丝工艺参数制备的GR/PAN复合纳米纤维膜的过滤效率为98.86%,过滤阻力为110.30 Pa。
The GR/PAN composite nanofiber membrane was prepared by electrostatic spinning technology through mixing graphene(GR)nanoparticles into polyacrylonitrile(PAN)spinning solution.The influences of PAN mass fraction,GR dosage,spinning voltage and receiving distance on the morphology and filtration performance of GR/PAN composite nanofiber membrane were studied,and it was found that the optimal spinning process parameters were PAN mass fraction at 14.0%,GR dosage at 1.5%,spinning voltage at 26 kV,receiving distance at 14 cm and injection speed at 1 mL/h.The GR/PAN composite nanofiber membrane prepared by these process parameters had filtration efficiency of 98.86%and filtration resistance of 110.30 Pa.
