摘要： An electro-optically active polymer gel material comprising a high molecular weight alignment polymer adapted to be homogeneously dispersed throughout a liquid crystal to control the alignment of the liquid crystal molecules and/or confer mechanical stability is provided. The electro-optically active polymer gel comprises a homogenous gel in which the polymer strands of the gel are provided in low concentration and are well solvated by the small molecule liquid crystal without producing unacceptable slowing of its electrooptic response. During formation of the gel, a desired orientation is locked into the gel by physical or chemical cross-linking of the polymer chains. The electro-optically active polymer is then utilized to direct the orientation in the liquid crystal gel in the “field off” state of a liquid crystal display. The electro-optically active polymer also provides a memory of the mesostructural arrangement of the liquid crystal and acts to suppress the formation of large scale deviations, such as, for example, fan-type defects in a FLC when subjected to a mechanical shock. A method of making an electro-optically active polymer gel material and an electrooptic device utilizing the electro-optically active polymer gel of the present invention is also provided.

摘要翻译： 提供一种电光活性聚合物凝胶材料，其包含适于均匀分散在液晶中以控制液晶分子取向和/或赋予机械稳定性的高分子量对准聚合物。 电光活性聚合物凝胶包含均匀的凝胶，其中凝胶的聚合物链以低浓度提供并且被小分子液晶很好地溶剂化，而不会导致其电光响应的不可接受的减慢。 在形成凝胶期间，通过聚合物链的物理或化学交联将期望的取向锁定在凝胶中。 然后使用电光活性聚合物将液晶凝胶中的取向引导到液晶显示器的“截止”状态。 电光活性聚合物还提供液晶的介观结构布置的记忆，并且用于抑制大尺度偏差的形成，例如当受到机械冲击时FLC中的扇形缺陷。 还提供了制造电光活性聚合物凝胶材料的方法和利用本发明的电光活性聚合物凝胶的电光装置。

摘要： Compositions suitable for use as encapsulants are described. The inventive compositions include a high molecular weight polymeric material, a curing agent, an inorganic compound, and a coupling agent. Optional elements include adhesion promoting agents, colorants, antioxidants, and UV absorbers. The compositions have desirable diffusivity properties, making them suitable for use in devices in which a substantial blocking of moisture ingress is desired, such as photovoltaic (PV) modules.
