摘　　要：采用直接喷涂法和共混静电纺法制备银纳米线(AgNWs)改性聚偏氟乙烯(PVDF)静电纺膜,比较2种方法对改性PVDF静电纺膜性能的影响。结果表明:AgNWs直接喷涂于纯PVDF静电纺膜表面得到的改性PVDF静电纺膜,抑菌性能优异,水接触角较小,纤维直径及膜的透气率、孔隙率、断裂强力、断裂伸长率、过滤效率、过滤阻力等较纯PVDF静电纺膜变化不明显。与直接喷涂法相比,共混静电纺法制备的改性PVDF膜中纤维直径更细,但因AgNWs包埋在纤维内部,故抗菌性能不及直接喷涂法制备的改性PVDF静电纺膜。为获得优异的抗菌性能,可选用直接喷涂法制备AgNWs改性PVDF静电纺膜。Silver nanowires(AgNWs)modified polyvinylidene fluoride(PVDF)electrostatic spinning films were prepared by direct spraying method and blended electrostatic spinning method.And the effects of two methods on the performance of modified PVDF electrostatic spinning films were compared.The results showed that the modified PVDF electrostatic spinning films obtained by AgNWs directly sprayed on the surface of pure PVDF electrostatic spinning films had excellent antibacterial property,small water contact angle,and no obvious changes in fiber diameter,film air permeability,porosity,breaking strength,breaking elongation,filtration efficiency and filtration resistance compared with pure PVDF electrostatic spinning films.Compared with the direct spraying 2023method, the fiber diameter of modified PVDF film prepared by the blended electrostatic spinning method was finer, but the antibacterial property was inferior to that of modified PVDF film prepared by the direct spraying method, because AgNWs was embedded in fibers. In order to obtain excellent antibacterial properties, AgNWs modified PVDF electrostatic spinning films can be prepared by direct spraying method.
