|Abstract:||Present work deals with findings on dielectric behaviour and a.c. conduction with structural studies in a [(PEOSiO2):NH4SCN] polymer nano composite electrolyte system. The formation of nano composite and structural behaviour of electrolyte was studied by XRD and SEM images. The effect of filler and salt on conductivity behaviour of PEO based nano composite polymer electrolyte has been investigated by the impedance spectroscopy at various temperatures. The variation of dielectric permittivity and dielectric loss with frequency was carried out at room temperature. The a.c. conductivity seems to follow the universal power law. The real and imaginary part of permittivity was calculated from the relation.|
