Abstract
Two groups of polymer dispersed liquid crystals (PDLCs) have been studied, results indicated ,when the liquid crystals (LCs) and the UV monomers before curing in the preparation had poor miscibility, the PDLCs showed poor electro-optical properties. Then, we obtained a series of LC mixtures based on E8 and B001, the clearing point of which changed from 71.6 °C to 142.0 °C. The further study on the effect of temperature on the electro-optical properties of PDLCs indicated that PDLCs with high temperature resistance may be obtained by increasing the clearing point of LCs coupled with manipulating other LC parameters.
