| Abstract: | An electro-optical characterisation of a polymer-dispersed liquid crystal (PDLC) based on unsaturated polyester (UP) resin,
recently prepared in our laboratory, is presented. Transmittance and response times as a function of an electric field applied
to the sample, have been measured taking into account also the morphological aspects of various samples. The experimental
results confirm the theoretical data previously calculated on the base of the dimensions of the liquid-crystal droplets inside
the polymeric matrix. Our analysis on this new material suggests the possibility of employing such a PDLC to realise electro-optical
devices.
