We investigated pinning of inorganic nanosheets in a colloidal liquid crystalline state prepared by exfoliation of layered crystals in a solvent in order to convert them to fluid membranes, as a first step of constructing inorganic biomimetic membranes. Liquid crystalline niobate nanosheets were pinned in an aqueous system through careful washing of the nanosheets, growth of the liquid crystal domains, and application of an electric field in the direction perpendicular to gravity which causes sedimentation of the nanosheets. Membrane-like structures will be realized if we control the domain growth more carefully.

我们研究了通过在溶剂中剥离层状晶体而制备的胶体液晶态无机纳米片的钉扎，以便将其转化为流体膜，作为构建无机仿生膜的第一步。 通过仔细清洗纳米片、生长液晶域以及在垂直于重力的方向施加电场导致纳米片沉降，将液晶铌酸盐纳米片固定在水性系统中。 如果我们更仔细地控制域的生长，就可以实现膜状结构。
