Abstract

UNA NUEVA CELULA Y MATERIAL DE MODULACION DE LUZ CRISTALINA LIQUIDA SE CARACTERIZAN POR EL MATERIAL DE MODULACION DE LUZ CRISTALINA DE CRISTAL LIQUIDO Y POLIMERO, SIENDO EL CRISTAL LIQUIDO UN CRISTAL NEUMATICO QUIRAL (16) QUE TIENE ANISOTROPIA DIELETRICA POSITIVA Y QUE COMPRENDE MATERIAL QUIRAL EN UNA CANTIDAD EFECTIVA PARA FORMAR TEXTURAS PLANAS RETORCIDAS Y CONICAS FOCALES, ESTANDO EL POLIMERO DISTRIBUIDO EN CAMPOS SEPARADOS DE FASE (15) EN LA CELULA DE CRISTAL LIQUIDO EN UNA CANTIDAD QUE ESTABILIZA LAS TEXTURAS PLANAS Y RETORCIDAS Y CONICAS FOCALES EN AUSENCIA DE UN CAMPO Y PERMITE QUE EL CRISTAL LIQUIDO CAMBIE TEXTURAS TRAS AL APLICARSE UN CAMPO. EN UNA REALIZACION, EL MATERIAL ES DIFUSOR DE LUZ EN UNA CONDICION NO CONMUTADA DE CAMPO Y OPTICAMENTE CLARA EN CONDICION CONMUTADA DE CAMPO, MIENTRAS EN OTRA REALIZACION EL MATERIAL ES OPTICAMENTE CLARO EN UNA CONDICION DE NO CONMUTACION DE CAMPO Y DIFUSOR DE LUZ EN UNA CONDICION DE CONMUTACION DE CAMPO. EN OTRA REALIZACION MAS , EL MATERIAL EXHIBE ESTABILIDAD EN NINGUN CAMPO EN UN ESTADO REFLECTOR DE LUZ, UN ESTADO DE DIFUSION DE LUZ Y UN ESTADO MULTIPLE DE REFLEXION ESTABLE ENTRE SI, ASI COMO ES OPTICAMENTE CLARO EN PRESENCIA DE UN CAMPO.
