Abstract
A resizable polymer-stabilized, thermotropic liquid crystal device formulation is used in passive or active light-regulating and temperature-regulating films, materials and devices, including construction materials. Implementations of the device may be composed of five basic elements: one or more transparent substrates, a transparent surface treatment, a liquid crystal mixture, a stabilizing polymer, and spacer beads. The polymer-stabilized liquid crystal is coated and cured on at least one substrate. The transparent surface treatment and the stabilizing polymer network are selected to provide phase separation, curing, and adhesion within the LC mixture. The substrate or substrates may be polarizing or nonpolarizing.
