ABSTRACT --

Composite samples were prepared in the form of thin films (50-80pm) by solution cast techniques for different weight fractions of FTT in P M F matrix. Samples were a.c. poled at a temperature of -180OC. The a. c. poling at elevated temperature considerably enhances the dielectric constant and is found to be a more efficient way of poling composite films than conventional d.c. poling. SEM and XRD studies were done to correlate the increment in dielectric constant with structural modification.
