Abstract

Composite thin films of PbTiO₃ nanocrystals and high-transparency PEK-c polymer for applications in electro-optical devices were prepared using the spin coating technique. The size of the PbTiO₃ nanocrystals was estimated to be 30-40 nm using a transmission electron microscope. The transmission technique, a simple method for measuring the electro-optic coefficients of poled composite polymer films was developed. The electro-optic coefficient γ₃₃ of poled PbTiO₃/PEK-c composite polymer films was measured to be 18.34 pm V^-1 at 633 nm under room temperature. The index at 633 nm and the dielectric constant at 100 kHz under room temperature were determined to be 1.65248 and 7.32, respectively. The figure of merit F₂ = n⁷γ²/ε was estimated to be 1546, showing very good electro-optical properties.
