采用静电纺丝技术制备聚乙烯醇（PVA）/聚氧化乙烯（PEO）共混纳米纤维膜，测试共混纤维膜的拉伸力学性能，采用SEM观察其微观形貌和结构，利用TGA和DSC分析共混纤维膜的热学性能，考察PEO与PVA共混比例对纤维膜性能的影响.结果表明：PEO加入过多或过少对共混纤维膜结构均无明显改善，当PVA∶PEO质量比为5∶5时，所得纤维膜成丝性和成膜性最佳，膜中纤维线密度最小且粗细均匀；与纯纺纤维膜相比，不同共混比例PVA/PEO纤维膜的力学性能均有不同程度提升，当PVA与PEO质量比为7∶3时其断裂强度和断裂伸长率较纯PVA分别提高了66%和1545.71%；PVA/PEO共混纤维膜的热稳定性优于纯PVA纤维膜，但PEO加入量的变化对共混纤维膜热学性能的影响较小.

The poly vinyl alcohol (PVA)-poly ethylene oxide (PEO) blend nanofiber films was produced with electrospin-ning technology. The mechanical properties of blend films were tested, fiber microstructure was investigated by SEM, and thermal properties of films were investigated with TGA and DSC. The effects of mass ratio of PVA to PEO on the properties of blend films were analyzed. The results indicate that too much or too little PEO have no obvious improvement on the ability of forming wires of blend films, and when the mass ratio of PVA to PEO is 5∶5, the blend film has good ability of forming wires, the fiber is fine and uniform. Compared with pure films, the mechanical properties of blend films are improved in different degrees, when the mass ratio of PVA to PEO is 7∶3, the elongation and strength of blend films increase by 1 545.71%!and 66%, respectively. The thermal stability of PVA/PEO blend films are better than those of pure films, but the amount of PEO has little effect on the thermal properties of blend films.
