Conducting polymer poly(O-toluidine) (POT) doped with dodecyl benzene sulfonic acid was prepared by the chemical polymerization with the help of ammonium persulphate (NH4)2S2O8 as an oxidizing agent. This polymer was blended with different weight ratios (0%, 10%, 15%, 25%, 35%, 45%, 50%) of poly(ethylene oxide) (PEO) to produce nano conducting polyblend POT-DPSA/PEO, prepared by the spin coating method, and deposited on a glass substrate. The surface morphology was studied by scanning electron microscope. The optical properties of a prepared film was studied from the absorbance spectra at wavelengths 300–1100 nm. The analysis of optical measurement data shows the direct transition with the energy gap decreasing from 2.80 eV to 2.25 eV, as the content of PEO increases from 0% to 50%.
