LIGHT CONTROLLABLE MATERIAL, LIGHT CONTROLLABLE FILM AND METHOD OF MANUFACTURING LIGHT CONTROLLABLE FILM

摘要

PROBLEM TO BE SOLVED: To provide a light controllable film which is changed in light transmittability by the presence or absence of an electric field, is controllable in the entire incident light quantity, does not flocculate and settle light polarization particles, can exhibit a stable light controllable function and can facilitate manipulation for spacing maintenance, etc., of a substrate in manufacturing and a method of manufacturing the same. SOLUTION: This light controllable material contains a high-molecular medium which consists of a silicone resin having a substituent possessing an ethylenically unsaturated bond and a photopolymerization initiator and is cured by irradiation with UV rays and a light polarization suspension which is dispersed with particles having an aspect ratio of 1.1 to 4.0 in a dispersion medium in a flowable state. The dispersion medium in the light polarization suspension can be separated in phases from the high-polymer medium and the cured matter thereof.
