Description
Summary:The detailed functionality of 0-3 paint/lead magnesium niobate-lead titanate (PMN-PT) composite films is investigated in terms of their dielectric and electric transport characteristics. The Paint/PMN-PT composite films have been fabricated by a conventional cost effective paint brushing technique. 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 increase with an increase of filler content, and temperature, providing information on the functionality of the films. The results reveal that the AC conducitivity, σ AC, obeys the relation σ AC = Aω s , and exponent s, was found to decrease by increasing the temperature.
