Abstract

We report the assembly of polyelectrolyte multilayer (PEM) films at the interfaces of thermotropic liquid crystal (LC) droplets dispersed in an aqueous phase. Exposure of PEM-coated droplets to surfactant slowed the bipolar-to-radial ordering transition of the LCs by 2 orders of magnitude relative to naked droplets. This shows that PEMs can be used to influence the interactions of analytes with the LC cores of the droplets, allowing tuning of the LC emulsion sensing properties.

摘要

我们报道了在分散于水相中的热致液晶（LC）液滴界面处组装聚电解质多层（PEM）膜的情况。相对于裸液滴，将涂覆有PEM的液滴暴露于表面活性剂会使LC的双极到径向有序转变减慢2个数量级。这表明PEM可用于影响分析物与液滴LC核的相互作用，从而实现对LC乳液传感特性的调节。
