我们报告的快速电光开关（响应时间0.1毫秒）的蓝相聚合物模板具有广泛的温度范围内的热力学稳定性和无荧光的性能。该聚合物填充聚合物模板，该聚合物模板施加具有立方对称性和亚微米周期的周期性结构。在无场状态下，聚合物模板是光学各向同性的。施加的电场引起非零光学延迟。因此，该方法结合了蓝相（具有亚微米周期性的立方结构）的有益结构和光学特征以及纳米填料的上级热力学稳定性和电光切换能力。
We report on fast electro-optic switching (response time 0.1 ms) of a blue-phase-polymer templated nematic with a broad-temperature range of thermodynamic stability and hysteresis-free performance. The nematic fills a polymer template that imposes a periodic structure with cubic symmetry and submicron period. In the field-free state, the nematic in polymer template is optically isotropic. An applied electric field causes non-zero optical retardance. The approach thus combines beneficial structural and optical features of the blue phase (cubic structure with submicron periodicity) and superior thermodynamic stability and electro-optic switching ability of the nematic filler.
