Abstract

Abstract : Ni0·3 Co0·2 Zn0·5 Fe2 O4 –SiO2 /dodecylbenzene sulphonic doped polypyrrole composites with core–shell structures have been fabricated by in situ chemical polymerisation method. The structure of samples has been characterised by fourier transform infrared and X-ray diffraction. The morphologies have been observed by scanning electron microscopy and transmission electron microscopy. The electromagnetic properties have been tested by four-probe conductivity tester and vibrating sample magnetometer. Results show that the Ni0·3 Co0·2 Zn0·5 Fe2 O4 –SiO2 /dodecylbenzene sulphonic doped polypyrrole composites have been synthesised successfully. The M s value achieves 13·68 emu g −1, and the conductivity reaches 23·5 S cm −1 . The probable formation mechanism of the Ni0·3 Co0·2 Zn0·5 Fe2 O4 –SiO2 /dodecylbenzene sulphonic doped polypyrrole composites has also been investigated based on the experimental results.
