摘　　要：将聚乙烯吡咯烷酮与含氢硅油共混作为纺丝溶液,用静电纺丝法制备了聚乙烯吡咯烷酮(PVP)/含氢硅油复合纤维膜,考察了PVP和含氢硅油用量对空气过滤效率的影响。研究发现,PVP含量7%,硅油含量14%,无水乙醇作为溶剂配制溶液,通过静电纺丝制备的复合纤维膜空气过滤效率达到81%,过滤效率达到最高。同时,利用红外光谱仪(FTIR)和扫描电子显微镜(SEM)对复合材料的结构和形貌进行了表征。通过扫描电子显微镜(SEM)得出结论,随着PVP添加量的增大,纺丝直径显著增大,纺丝的排列方式由缠绕变为交错。含氢硅油可以减少表面缺陷并降低水蒸气和溶剂对纤维膜的破坏。通过红外光谱仪(FTIR)得出结论,PVP含量7%,硅油含量14%对应样本红外图谱,同时具有PVP和含氢硅油的特征吸收峰。With polyvinylpyrrolidone （PVP）/hydrogen silicone oil blend as the spinning solution, PVP/hydrogenated silicone oil composite fiber membrane was prepared by electro spinning. The influence of mixing ratio on the filtration efficiency of the composite fiber membrane was investigated. The results show that in the conditions of the PVP content of 7%, the content of silicone oil of 14% and ethanol as the solvent, the air filtration efficiency of the composite fiber membrane is 81%, and the filtration efficiency reaches the maximum. At the same time, the structure and morphology of the composites were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. The results indicate that with the increase of PVP content, the diameter of spinning increase significantly, and the arrangement of spinning turns from winding into interlacing. Additionally, the sample with 7% PVP addition and 14% silicone oil addition has the characteristics characteristic absorption peaks of hydrogen silicone and PVP in the infrared spectra.
