中文摘要：
将溶胶-凝胶法和新型双喷丝头静电纺丝技术相结合，制备了CoFe2O4—SiO2电纺纳米纤维材料。利用热分析法（TpDTA）、X射线衍射（XRD）、扫描电镜（SEM）、透射电镜（TEM）和振动样品磁强计（VSM）等测试手段，表征了所研制纳米纤维的晶型结构、纤维形貌以及磁学性能.研究结果表明，样品中CoFe2O4为单畴结构，纤维直径在100nm左右，非晶态SiO2的存在有效抑制了CoFe2O4晶粒的生长；煅烧温度对纤维形貌和晶型结构有较大影响，随着煅烧温度的升高，饱和磁化强度（Ms）和剩余磁化强度（Mr）均增大，但矫顽力（Hc）和剩磁比（Mr/Ms）呈波动变化。
英文摘要：
CoFe2O4-SiO2 nanofiber materials were prepared by a two-spinneret electrospinning technology, combined with sol-gel method. The crystal structure, morphology and magnetic properties of the nanofibers were characterized by thermal analysis （TG-DTA）, X-ray diffraction （XRD）, scanning electron microscope （SEM）, transmission electron microscope （TEM）, and vibrating sample magnetometer （VSM）. The results show that, CoFe2O4 in the sample is one-domain structure, and the fiber diameter is about 100 nm. Furthermore, the growth of CoFe2O4 grain is restricted effectively with the existence of amorphous SiO2. And calcining heat exert a tremendous influence on the morphology and crystal structure of the fibers. With the rise of treatment temperature, both saturation intensity （Ms） and remanent magnetization （Mr） increase, while coercive force （Ho） and remanence ratio （Mr /Ms） fluctuate.
