Effect of Tin Doping on DC Electrical Properties of Polyaniline

The Sn doped polyaniline hydrochloride is synthesized by chemical oxidation method at room temperature. The SnCl4 is used as dopent.The DC electrical conductivity of the samples is measured and logs Vs 1/T plot is drawn for explanation of equation (1).The aplot is nonlinear. The values of activation energy are found to in range of 0.05 eV -0.3eV which is quite agreement with the values reported in the litreture.It Is observed that the DC electrical conductivity increases with increasing SnCl4 molar concentration. FTIR spectra of the samples is obtained in the range of 400-4000 cm-1 with 4 cm-1 deviation. The structure is discussed on the basis of spectra.
