The interest in research and development ofplasticliquid crystal technology originates from the stabilization of liquid crystals with a polymer matrix for manufacturing of largearea flexible electro-optical films which can be used as electrically switchable shutters, panels and privacy windows in the building, residential and transportation sectors, as well as reflective displays. In figure 1, we show typical examples of PDLC applications as electro-optical windows. The display applications of PDLC are not within the scope of the present article.
