近年来,有关将高分子(聚合物)材料与液晶复合体的光散射效应用于显示及调光器件方面的研究极为活跃。此种聚合物·液晶复合体是采用将直径几μm 以下的液晶球状小滴(微滴)分散在聚合物中,或在网状聚合物中充填液晶构成的,通过施加电压使液晶分子的排列方向同电场方向相一致,从而使聚合物与液晶的折射率互相配合而达到使用的。例如,在无电场的状态下,液晶小滴的光轴是无规则的,液晶的有效折射率同聚合物的折射率不一致,因光散射效应而呈现不透明的白色状态。一旦
In recent years, research on the light scattering effect of a polymer (polymer) material and a liquid crystal composite for display and dimming devices has been extremely active. Such a polymer / liquid crystal composite is formed by dispersing liquid crystal spherical droplets (droplets) having a diameter of several micrometers or less in a polymer or filling a network polymer with liquid crystal, and by applying a voltage to align the liquid crystal molecules Direction consistent with the direction of the electric field, so that the polymer and liquid crystal refractive index with each other to achieve the use of. For example, in the absence of an electric field, the optical axis of liquid crystal droplets is irregular. The effective refractive index of the liquid crystal does not agree with the refractive index of the polymer, and the opaque white state occurs due to the light scattering effect. once
