    • Disclosed is a method for manufacturing light control particles usable for a light control material comprising: a resin matrix made from a polymeric medium that is cured by irradiating with an energy beam; and a light control suspension comprising: a dispersing medium; and the light control particles that are dispersed in the dispersing medium so as to be in a flowing state, the method comprising the step of granulating after mixing elemental molecular iodine (A), an alkaline earth metal iodide (B), and a heterocyclic compound (C) with each other in a medium, wherein in the step of granulating, reaction is carried out in the presence of methanol in an amount of not less than 50 parts by mass but not more than 110 parts by mass relative to 100 parts by mass of the whole of components (A), (B) and (C). In this way, it is possible to provide a method for manufacturing light control particles wherein the effect of water is decreased in a granulating step of the method in order to yield effectively light control particles having a particle size and shape optimal for light control material and further a good reproducibility is attained.
    • 公开了一种制造可用于光控制材料的光控粒子的方法,包括:由聚合物介质制成的树脂基体,其通过用能量束照射而固化; 和光控悬浮液,其包含:分散介质; 以及分散在分散介质中以使其处于流动状态的光控粒子,该方法包括在将元素分子碘(A),碱土金属碘化物(B)和杂环化合物 (C),其中在制粒步骤中,在甲醇存在下,相对于100份,相对于100份,不少于50质量份,但不超过11​​0质量份,进行反应 组分(A),(B)和(C)的总质量。 以这种方式,可以提供一种制造光控粒子的方法,其中在该方法的造粒步骤中水的作用降低,以便有效地产生具有对于光控材料最佳的粒度和形状的光控制颗粒,以及 进一步获得良好的再现性。
