We developed polymer-dispersed liquid crystals (PDLCs) that effectively scatter light both in the visible and near-infrared ranges simultaneously. Such PDLCs are characterized by an optimal size distribution of nematic liquid crystal droplets within 0.4 − 3 µm, which is achieved due to the specially selected copolymer, the elaborated liquid crystal material as well as the proper cooling mode from the isotropic phase. These PDLC films provide electrically controlled light scattering modulation in the spectral range 300 − 2300 nm with the response time around 10 ms.

在可见光和近红外范围内具有电控光散射的聚合物分散液晶

我们开发了聚合物分散液晶 (PDLC)，可同时有效地散射可见光和近红外范围内的光。这种 PDLC 的特点是向列液晶液滴的最佳尺寸分布在 0.4 - 3 µm 内，这是由于特别选择的共聚物、精心制作的液晶材料以及各向同性相的适当冷却模式而实现的。这些 PDLC 薄膜在 300 - 2300 nm 的光谱范围内提供电控光散射调制，响应时间约为 10 ms。
