摘　　要：以Fe(NO3)3·9H2O和Zn(NO3)2·6H2O为原料,采用改进的柠檬酸盐前驱物法合成了片状ZnFe2O4,进一步通过原位聚合反应得到了聚苯胺(PANI)/ZnFe2O4纳米复合物。利用X射线粉末衍射、扫描电子显微镜、透射电子显微镜、红外光谱以及荧光光谱等测试技术对其进行了表征。实验结果表明,通过原位聚合反应PANI沉积在片状ZnFe2O4表面。X射线粉末衍射和红外光谱进一步证实了PANI/ZnFe2O4纳米复合物的生成。ZnFe2O4的引入提高了PANI的荧光发光性能和热稳定性。Sheet-like ZnFe2O4 was prepared by means of a modified citrate precursor method with Fe（NO3）3·9H2O and Zn（NO3）2·6H2O as starting materials.Polyaniline（PANI）/ZnFe2O4 nanocomposite was obtained by the in-situ polymerization of aniline in the presence of ZnFe2O4.The as-prepared samples were characterized by means of X-ray diffraction,scanning electron microscopy,transmission electron microscopy,infrared and fluorescence spectroscopies.The results show that PANI was deposited on the surface of sheet-like ZnFe2O4.X-ray diffraction and infrared spectra further confirmed the formation of PANI/ZnFe2O4 nanocomposite.Introducing ZnFe2O4 into polymer matrix enhanced the fluorescent emission intensity and thermal stability.
