nanocomposites have been studied at room
temperature and normal pressure. Energy band gap of
these materials are determined by UV-VIS absorption
spectra in the wavelength range 264nm–1936nm by
spectrophotometer. In this work the experimental
results obtained from the UV-VIS spectra are
reported for nanocomposites of different wt
percentages (10% -50%.). Characteristic peak around
800 nm was observed in all the nanocomposites
confirming the formation of polypyrrole. The work
highlights the optical properties of these polymer
nanocomposites for making them a suitable
candidate for optoelectronic devices
