采用静电纺丝技术制备了嵌入沸石咪唑骨架材料-8(ZIF-8)的聚乙烯吡咯烷酮(PVP)多孔纤维,进一步研究ZIF-8与PVP的用量配比对ZIF-8/PVP纳米纤维膜苯吸附性能的影响。结果表明:在ZIF-8与PVP质量比为1.3条件下合成的复合纳米纤维具有良好的苯吸附性能,吸附容量从380mg/g提升到580mg/g,这主要是由于多孔PVP和ZIF-8构成的多级结构的协同效应所致。
ZIF-8 layered polyvinylpyrrolidone(PVP) fibers were prepared by electrospinning.ZIF-8 was blended with polyvinylpyrrolidone to prepare composite fibers with uniform morphology and excellent properties during electrospinning.The results showed that the composite fiber with 1.3 mass ratio of Zif-8 to PVP had good benzene adsorption capacity,which increased from 380mg/g to 580mg/g,this may be due to the synergistic effect of multi-level structures composed of porous PVP and ZIF-8.
