This article presents, for the first time, the detailed functionality of 0-3 Paint/PMN-PT composite films concerning their dielectric and electric transport characteristics. Paint: Lead Magnesium Niobate-Lead Titanate (Paint/PMN-PT) composite films have been fabricated by the conventional cost effective paint brushing technique. The dielectric parameters of the composite films were calculated by the measurement of capacitance and dielectric loss. The properties investigated include, dielectric constants, ε' and ε'' as a function of temperature, frequency and composition. From the foregoing parameters, it is indicated that the dielectric constants and A. C. conductivity (σAC) increase with increase of filler content, and temperature, implying functionality of the films. The results reveal that σ_AC obeys the relation σ_AC = Aω^s, and exponent s, was found to decrease by increasing the temperature. It was found that, the correlated barrier hopping (C. B. H.) is the dominant conduction mechanism in nanocomposite films fabricated.
