abstract This study intends to present some further research in polymer-dispersed liquid crystal (PDLC) systems [1]. These PDLC type cells were produced based on a low-cost commercial polymer (PVC) and liquid crystal E48 (Merck), using a modified solvent preparation method (SIPS). These cells were characterized electro-optically and by low frequency dielectric relaxation (20 Hz to 1 MHz) experiments. Results are encouraging; the prepared composites show regular microstructures and optical transmittance changes induced by the electric field, introducing an alternative way of producing low-cost PDLC electro-optical cells.
