摘　　要：以聚乙烯吡咯烷酮(PVP)为络合剂与Mn(CH3COO)2和La(NO3)3·6H2O反应制得前驱体溶液,用静电纺丝法制备了PVP/Mn(CH3COO)2·La(NO3)3纤维,经煅烧得到具有微孔结构的La0.96Mn0.96O3纤维。对所制备纤维采用红外光谱分析(IR)、X射线衍射(XRD)分析、扫描电镜(SEM)等手段进行了表征。结果表明煅烧前后纤维的性质和形貌发生很大变化。PVW Mn（ CH3COO ）2·La （NO3 ）3 composite fibers were prepared by electrospinning technique with manganese acetate and PVP as starting materials. After calcining the above precursor fibers, La0.96Mn0.96O3 fibers were obtained successfully. The La0.96Mn0.96O3 miero/nano fibers were characterized by, FTIR, XRD and SEM, respectively. Results showed that the crystalline phase and morphology of La0.96Mn0.96O3 fibres were greatly changed by the calcination temperature.
