Abstract
We obtained polymer dispersed nematic liquid crystal films E7/PMMA. In order to induce anisotropy and consequently electrical polarization, the films have been hot stretched and pressed.
We studied the dependence of the polarization upon temperature, frequency and amplitude of the applied electric field. High values of the order of μC/cm2, have been obtained. The frequency dependence of the polarization indicates relaxation times of the order of milliseconds.
