Abstract
AC impedance spectroscopy is applied to monitoring the chemical-physical condition of polymer dispersed liquid crystals (PDLC). The results define an approach for non-destructive evaluation as the PDLC is designed into informational displays. Response. functions are linked to electrical properties of the constituents through mixture relations. Resistivity is established as being much more sensitive than permittivity to the PDLC state. Consideration is given to treating explicitly the large interphasal region found surrounding each liquid crystal droplet in the continuous matrix.
