1c09 マイクロリンクルの溝に閉じ込められた液晶における周期的欠陥構造(物理・物性,口頭発表,2012年日本液晶学会討論会)

抄録

Microwrinkles are strain-induced surface undulations, which form on an elastomer surface capped by a hard thin layer. The sinusoidal grooves can serve as open capillary channels, providing a unique micro-confinement of liquids. When a liquid crystal is confined there, its alignment can be distorted and topological defects may be produced due to the specific boundary conditions. Here, we report periodic defect structures self-organized in a nematic or smectic-A liquid crystal confined within microwrinkle grooves.
