Optical Properties Of Doped Polyaniline

K.Gupta, P.C.Jana

Comparison of electrical conductivity and optical absorption spectrum of undoped PANI(polyaniline) and PANI doped with cobalt chloride, ferric chloride, copper chloride, hydrochloric acid is made. Absorption line shape is best fitted with Gaussian oscillators with different resonance frequencies, damping factors and relative oscillator strengths. copper chloride doped PANI is promising material for electronic application.
