    • Switchable gas permeation membranes in which a photo-switchable low-molecular-weight liquid crystalline (LC) material acts as the active element, and a method of making such membranes. Different LC eutectic mixtures were doped with mesogenic azo dyes and infused into track-etched porous membranes with regular cylindrical pores. Photo-induced isothermal phase changes in the imbibed mesogenic material afforded large, reversible changes in the permeability of the photo-switchable membrane to nitrogen. For example, membranes imbibed with a photo-switchable cyanobiphenyl LC material demonstrated low permeability in the nematic state, while the photo-generated isotropic state demonstrated a 16×-greater sorption coefficient. Both states obey a high linear sorption behavior in accordance with Henry's Law. In contrast, membranes imbibed with a photo-switchable phenyl benzoate LC material showed the opposite permeability behavior to the biphenyl-imbibed membrane, along with nonlinear sorption behavior.
    • 可切换的低分子量液晶(LC)材料作为有源元件的可切换气体透过膜及其制造方法。 不同的LC共晶混合物掺有介晶偶氮染料,并注入具有规则圆柱孔的轨道蚀刻多孔膜。 吸收的介晶材料中的光诱导等温相变提供了可光切换膜对氮的渗透性的大的可逆变化。 例如,用可光切换的蓝色联苯LC材料吸收的膜在向列状态下表现出低渗透性,而光生各向同性状态表现出16×更高的吸附系数。 根据亨利定律,这两个州都服从高线性吸收行为。 相比之下,吸收有可光切换的苯甲酸苯酯LC材料的膜与联苯吸收膜呈现相反的渗透性,以及非线性吸附行为。
