Solid polymer electrolyte film samples of hydroxypropyl methylcellulose (HPMC) / poly vinylalcohol (PVA) blends embedded with 1% - 4% (wt.%) of copper oxide (CuO) nanoparticles were synthesized by solution cast method. The prepared samples were analyzed for AC conductivity using LCR meter (ZM2376) with in the frequency range 50 Hz to 1 MHz at room temperature. Jonschers power law holds good for the plots of AC conductivity in the high frequency region. The plateau area of ac conductivity plots is used to compute DC conductivity. The acquired dc conductivity values are found to be consistent with the calculated conductivity value based on bulk resistance. By examining the complex electrical modulus, it can be concluded that the described polymer electrolytes exhibit non-debye type conductivity relaxation.
