We demonstrate the preparation of colloidal crystals at nematic liquid crystal–air interfaces by simultaneous photopolymerization and assembly. Polymer colloids are produced by polymerization-induced phase separation of 2-hydroxyethyl methacrylate in the non-reactive liquid crystal (LC) 4-cyano-4′-pentylbiphenyl (5CB) using an open-cell setup. Colloids adsorbed to the nematic 5CB–air interface form non-close-packed hexagonal crystals that cover the entire interface area. We examine the mechanism of growth and assembly for the preparation of LC-templated interfacial colloidal superstructures.

通过光聚合作用在液晶-空气界面形成向列胶体。

我们展示了通过同时光聚合和组装在向列液晶-空气界面制备胶体晶体。聚合物胶体是通过使用开孔装置在非反应性液晶 (LC) 4-氰基-4'-戊基联苯 (5CB) 中聚合诱导甲基丙烯酸 2-羟乙酯的相分离而产生的。吸附到向列 5CB-空气界面的胶体形成覆盖整个界面区域的非密堆积六方晶体。我们研究了制备液晶模板界面胶体超结构的生长和组装机制。
