    Polymer nanocomposite comprising 25 weight % of nano copper oxide (n-CuO) and poly (o-toluidine) [POT] is prepared. For the first time, we report the current–voltage (I–V) characteristics of this nanocomposite. Incorporation of n-CuO modifies the structural properties of POT. The X-ray diffraction (XRD) spectra indicate the bonding of CuO with the polymer matrix. The Band gap of the samples is estimated about 1.78 ​eV. FTIR spectra reveal presence of C–H, C–C bonds. SEM image recorded reveal substitution of n-CuO inside the POT matrix. I–V characteristic recorded at different temperature implies change in conducting behaviour of the polymer nanocomposite from conducting to semiconducting nature with change in temperature
