Abstract:

ZnFe2O4 nanoparticles were prepared by a modified citrate precursor method using Fe(NO3)3?9H2O and Zn(NO3)2?6H2O as starting materials. PANI/ZnFe2O4 nanocomposite was obtained by in-situ polymerization of aniline in the presence of ZnFe2O4 nanoparticles. The as-prepared samples were characterized by means of X-ray diffraction, scanning electron microscopy, infrared spectra and fluorescence spectra. The results showed that PANI was deposited on the surface of sheet-like ZnFe2O4 nanoparticles. X-ray diffraction and infrared spectra were further confirmed the formation of PANI/ZnFe2O4 nanocomposite. Introducing ZnFe2O4 nanoparticles into polymer matrix enhanced fluorescent emission intensity and thermal stability.
