采用溶胶-凝胶法与静电纺丝技术相结合制备了PVP/[Ni(NO3):+Fe(NO3)3]复合纳米纤维,在一定温度下进行热处理,得到尖晶石结构的NiFe2O4纳米纤维.利用TG-DTA、XRD、FTIR、SEM、TEM等分析手段对样品的组成及结构进行表征.TG-DTA分析表明,PVP/[Ni(NO3)2+Fe(NO3)3]复合纳米纤维的热处理温度高于450℃以后,质量恒定,总失重率为87.8%.XRD与FTIR分析表明,热处理温度高于600℃时,复合纳米纤维已经完全转变成尖晶石结构的NiFe2O4纳米纤维.SEM分析表明,所制备的PVP/[Ni(NO3)2+Fe(NO3)3]复合纤维直径在250～300 nm之间,NiFe2O4纳米纤维直径约100 nm,长度大于200μm.对NiFe2O4纳米纤维的形成机理进行了探讨.
PVP/[Ni(NO3)2 +Fe(NO3)3]composite nanofibers were prepared by combination of electrospinning and sol-gle method.The spinel-typed NiFe2O4 nanofibers were obtained by calcination of the composite nano fibers at definite temperatures and were characterized by TG-DTA,XRD,FTIR,SEM and TEM.TG-DTA analysis indicates that the mass of the PVP/[Ni(NO3)2 + Fe(NO3)3]composite nanofibers keeps constant above 450℃,and the total weight loss rate is 87.8%.XRD and FTIR analysis reveals that spinel-typed NiFe2O4 nanofibers are completely formed above 600℃.SEM observation manifests that the diameter of the composite fibers is 250-300 nm.The diameter of NiFe2O4 nanofibers is about 100 nm,and the length is greater than 200 μm.The formation mechanism of the NiFe2O4 nanofibers is also discussed.
