AC electrical behavior of a novel aromatic electro-optic polyimide was investigated in the temperature range 25°C to 300°C and covers frequency range from 1 Hz to 10 6 Hz. Three electrical quantities, ac impedance, conductivity and permittivity were reported. The experimental results show that the relative permittivity of aromatic electro-optic polyimide is temperature independent below 200°C, indicating that the chains below this temperature are nearly rigid. Above this temperature a relaxation process was observed with an activation energy 35 KJ/mole associated with a restricted rotational motion of the side chain chromophore. |
