Ferromagnetic polyaniline (PANI)/TiO2 nanocomposites were synthesized
by the oxidative polymerization of aniline with ammonium peroxydisulfate
(APS), in the presence of colloidal TiO2 nanoparticles and TiO2 nanotubes,
without added acid. The morphological, magnetic and structural properties
of the PANI/TiO2 nanocomposites were studied by SEM microscopy,
SQUID magnetometer and FTIR spectroscopy. The electrical conductivity
of synthesized nanocomposites was ~10-3 Scm-1. The room temperature
ferromagnetic response significantly depends on shape of TiO2
nanoparticles
