以聚乙烯吡咯烷酮(PVP)作为纺丝助剂,五水合四氯化锡(SnCl4·5H2O)作为前驱体,采用静电纺丝技术结合高温煅烧法成功制备了直径为(363±28)nm的多孔氧化锡纳米纤维膜.使用SEM表征了纤维膜的微观形貌和尺寸,利用X射线衍射仪(XRD)研究了焙烧温度对晶粒尺寸的影响,利用傅里叶变换红外光谱仪(FTIR)、热重和差热同步仪(TGA-DTA)及拉曼光谱仪(Raman)等研究了纤维膜的分子结构变化、热稳定性和物相结构.研究结果表明,固定两喷丝头间距15.0 cm、流速0.5 mL/h、电场强度1.1～1.4 kV/cm时,可以电纺出表面光滑、直径均一的纳米纤维膜;经900℃焙烧制备得到晶粒尺寸约12.27 nm的四方相金红石型晶体结构的氧化锡纤维膜.
