| Abstract: | Abstract: In this study poly(pentafluorostyrene)-ran-poly(4-vinylaniline) (PPFS-r-PVA) was synthesized by solution polymerization with AIBN utilized as an initiator. The dilute THF solution of the resultant copolymer was spin-coated onto clean Ag/Si(100) substrates, and then the copolymer film was electrically poled at 85 °C for 30 min using a plane poling method with a poling voltage of 7.0 kV. The pyroelectric coefficient was determined by a digital integral method and carried out with a charge integral instrument. It was observed that the average pyroelectric coefficient of the resultant PPFS-r-PVA was 20.4 µC/cm2K in the range of 20–45 °C, and the average dielectric loss is about 0.2298 between 3.2 × 104–1.0 × 106 Hz. |
