Abstract

In the 1980's, liquid crystals were combined with polymers to create an electrically-controllable light scattering medium. This type of material is known as polymer dispersion. Such mixtures have various forms depending on the type of liquid crystal used and on the concentration of the polymer. To date, the system most understood and extensively investigated are those with nematic liquid crystal type and with high polymer concentration (80-50 wt%) commonly called as polymer dispersed liquid crystals (PDLCs). These types of materials however have limitations in display applications like haze at wide angles of view. Because of these limitations, attention has shifted to systems with low polymer concentration (1-5 wt%) and with chiral doped nematic liquid crystals.
This study aims to determine properties of chiral-nematic ternary systems in low polymer concentration and the effect of UV exposure to the dispersions.
