XRD peaks demonstrate the interaction of nanoparticles with polymer matrix. It is evident from the dielectric data that observed change in dielectric parameters would result from appropriate changes in chain mobility due to nanoparticles-polymer interactions. FT-IR spectra represent the significant changes in intensity, shape and position of the different vibrational bands corresponding to -OH stretching, C-O-C stretching, C-H stretching and C-O-C in C-H stretching modes occur as a result of the incorporation of BaZrO3 nanofiller. Thermally stimulated discharge current (TSDC) and transient discharging current study presented the dipolar and interfacial type of relaxations.
