Abstract

Una película adecuada para usar como unidad moduladora de la luz de una válvula de luz de un dispositivo de partículas suspendidas (SPD), comprendiendo dicha película un polímero de matriz reticulado y teniendo gotitas de una suspensión de válvula de luz líquida distribuidas dentro del polímero de matriz reticulado, en la que dicho polímero de matriz reticulado está basado en siloxano, caracterizada porque dicho polímero de matriz reticulado tiene un contenido de fenilo suficiente para proporcionar al polímero de matriz reticulado un índice de refracción en el intervalo de aproximadamente 1,4700 a aproximadamente 1,4750, comprendiendo dicha suspensión de válvula de luz líquida una pluralidad de partículas suspendidas en un medio que comprende copolímero de metacrilato de octilo/metacrilato de 2-hidroxietilo.
