The next-generation windowpanes using liquid crystal composites

Abstract

We are developing a novel type of energy-saving windowpane which autonomously controls solar transmittance by seasonal change. It consists of polymer dispersed liquid crystals (PDLCs) and thermally switches the transparent/opaque states in the principle of phase transition behavior of liquid crystals (LCs) aggregated in polymerized mesogens. We will present our latest results and issues from now on. Additionally we will introduce the analysis of energy saving effect of residential windowpanes and the comparison with other technologies.
