Abstract

In the last decade, research in polymer dispersed liquid crystal (PDLC) has become a rapidly growing field. The classic PDLC system, consisting of a nematic droplet dispersed in a polymer, are used to produce thin polymer films which can be switched from a scattering, translucent to a transparent state by applying an electric field. PDLC systems are suitable for application in large-area light shutters (smart windows), flexible displays, projection displays with high brightness, storage devices and non-linear optical elements.
To date, the Liquid Crystals Laboratory had focused on researches on formulation, microscopy and thermal characterization. Only preliminary investigations on the electro-optic behavior at the IR region for PDLC systems have been conducted. This paper aims to further probe the transmission and relaxation behavior of PDLC's prepared via thermal and solvent induced phase separation (SIPS and TIPS). Experimentation on the said characteristics will be conducted in the visible region. Furthermore, the electrooptic characteristics will be linked to the morphology and other properties of the PDLC mixture.
