以二硫化钼(MoS2)粉体为原料、聚乙烯基吡咯烷酮(PVP)为表面活性剂,采用超声辅助液相剥离法制备了MoS2纳米片,利用静电纺丝技术制备了MoS2复合纳米纤维.采用紫外可见吸收光谱(UV-vis)、X射线衍射(XRD)、透射电子显微镜(TEM)、扫描电子显微镜(SEM)和拉曼光谱(Raman)表征了MoS2纳米片和复合纳米纤维的形貌、尺寸及分散性.结果表明,经超声辅助剥离制备的MoS2纳米片为单层或少层结构,其尺寸为50～100 nm.掺杂MoS2纳米片的复合纳米纤维具有光滑的表面和均匀的直径(～730 nm),MoS2纳米片在纤维内能均匀分散、无聚集,表明MoS2纳米片与PVP纤维有着良好的兼容性.
