Abstract

Mn<subscript>0·4</subscript>Zn<subscript>0·6</subscript>Nd<subscript>x</subscript>Fe<subscript>2-x</subscript>O<subscript>4</subscript>/polyaniline (PANI) nanocomposites with magnetic properties were prepared by in situ polymerisation of aniline in the presence of Mn<subscript>0·4</subscript>Zn<subscript>0·6</subscript>Nd<subscript>x</subscript>Fe<subscript>2-x</subscript>O<subscript>4</subscript> nanoparticles. The structure and morphologies of nanocomposites were characterised by X-ray diffraction, Fourier transform infrared (FTIR) spectroscopy and transmission electron microscopy (TEM). X-ray diffraction analysis shows that the size of Mn<subscript>0·4</subscript>Zn<subscript>0·6</subscript>Nd<subscript>x</subscript>Fe<subscript>2-x</subscript>O<subscript>4</subscript> nanocomposites increases with the increase in the Nd doped amount. The optimum doped amount of Nd was 0·075, and the optimum calcination temperature was 850°C. The ferrite particles are well embedded in PANI chains. The FTIR results further prove that the Nd doped manganese-zinc-ferrite/PANI composites have been synthesised. Images (TEM) showed that the nanocomposites presented a spherical structure with a magnetic core of Mn<subscript>0·4</subscript>Zn<subscript>0·6</subscript>Nd<subscript>x</subscript>Fe<subscript>2-x</subscript>O<subscript>4</subscript> and a conducting shell of PANI. The results showed that the electromagnetic properties of the Mn<subscript>0·4</subscript>Zn<subscript>0·6</subscript>Nd<subscript>x</subscript>Fe<subscript>2-x</subscript>O<subscript>4</subscript>/PANI composites were related to the mass ratio of PANI, the amount of Nd, the calcination temperature and the precipitation time.
