A new electro-optic polymer film PT/PEK-c has been prepared and investigated. This kind of film, especially c-axis oriented one, possesses good nonlinear optical properties. The structure of the film after poling was analyzed by x-ray diffraction. The result showed that the film was c-axis oriented. The transmittance of a 2.33-micrometer-thick film was measured in the wavelength range 320 to approximately 900 nm by means of a recording spectrophotometer. The transmittance of the film exhibited a sharp absorption edge at 360 nm. The optical band gap of the film was found to be 3.06 eV. The dielectric properties of PT/PEK-c film were investigated in terms of the dielectric constant (epsilon) r and the loss factor tg(delta) . They were measured by a capacitance bridge in the frequency range 1 X 102 approximately 3 X 106 Hz. The dielectric constant and the loss factor of a 2.33-micrometer-thick film at room temperature and 10 kHz frequency were determined to be 4.023 and 0.003, respectively.
