作者报道了通过掺杂纳米颗粒来扩大蓝相的温度范围。当将平均直径为3.7 nm的球形金纳米颗粒掺杂到呈现蓝相的多组分液晶混合物中时，蓝相的温度范围从0.5 ℃增加到5 ℃，而澄清温度降低了约13 ℃。我们认为，稳定蓝相的机制与聚合物稳定蓝相的机制相似：纳米颗粒在晶格向错中积累，稳定了整个蓝相结构。(C)2009日本应用物理学会DOI：10.1143/APEX.2.121501
The authors report the expansion of the temperature range of cholesteric blue phases by doping nanoparticles. When spherical gold nanoparticles with a mean diameter of 3.7 nm were doped in a blue phase-exhibiting multi-component liquid crystal mixture, the temperature range of the cholesteric blue phase increased from 0.5 to 5 degrees C, while the clearing temperature decreased by approximately 13 degrees C. We believe that the mechanism stabilizing the cholesteric blue phase is similar to that of polymer-stabilized cholesteric blue phases: the nanoparticles accumulate in the lattice disclinations, stabilizing the overall cholesteric blue structure.
