Abstract This work offers a promising approach for development of a temperature-responsive colorimetric display platform. For this purpose, uniform thermochromic microcapsules consisting of a cholesteric liquid crystal (CLC) core and a thin polyurethane shell layer were fabricated by conducting in-situ condensation polymerization at the interface of monodisperse CLC-in-water emulsion drops. Colloidal packing-driven microcapsule registry led to exact 2-dimensional positioning of CLC microcapsules into a holes-patterned flexible film stencil. Furthermore, we showed that the designated registry of different color types of CLC microcapsules on the stencil enabled development of a microwriting display technology capable of reversible text representation according to temperature change.

用于温度响应彩色显示器的胆甾型液晶微胶囊的二维胶体微图案化

摘要 这项工作为开发温度响应比色显示平台提供了一种有前景的方法。为此，通过在单分散 CLC-水乳液滴界面处进行原位缩聚，制备了由胆甾型液晶 (CLC) 核和薄聚氨酯壳层组成的均匀热致变色微胶囊。胶体填充驱动的微胶囊注册导致 CLC 微胶囊在孔图案柔性薄膜模板中的精确二维定位。此外，我们展示了模板上不同颜色类型的 CLC 微胶囊的指定注册表能够开发一种能够根据温度变化进行可逆文本表示的微写显示技术。
