| Abstract | ||
| The AC electrical conductivity σAC ,dielectric constant Є΄ and dielectric loss Є˝ for poly (Crystal Violet Terephthalate ) have been studied at frequencies that range from 100 KHz to 1300 KHz and in temperature range ( 22 –70 ) °C. The experimental result shows that the value of dielectric constant Є΄ slightly increases with increasing frequency which indicates that the major contribution to the polarization comes from orientation polarization , also the value of dielectric constant Є΄ increased with increasing temperature , and is due to the greater freedom of the movement of the dipole molecular chains .The dielectric loss Є˝ and AC electrical conductivity σAC increase with increasing frequency, such as Є and σAC dependant on frequency. | ||
