Description :
Polyaniline(PANI)-Titanium dioxide(TiO2 ) nanocomposite was prepared by onestep
in situ polymerization method in presence of TiO2 and was characterized via FTIR
spectra, UV-Vis. spectra thermogravimetric analysis and scanning electron microscopy.
SEM micrographs showed that the nanocomposite exhibited spherical morphology with
particle sizes about 70 nm. Both FTIR and UV-Vis. spectra indicate that polyaniline and
TiO2 are not simply blended. The thermal decomposition temperature of PANI is ~420 0
C in PANI- TiO2 nanocomposite, which is lower than that of PANI (~465 0 C).
