Recently, single-substrate flexible liquid crystal (LC) devices have attracted considerable attention because they can provide desirable shapes, small weight, flexibility, and rollability. In this work, we fabricate a flexible single-substrate thermoresponsive cholesteric LC (CLC) film by a facile method called photoenforced stratification method. Our fabricated single-substrate CLC film consists of microscale polymer containers filled with a CLC solution. Our results showed that the temperature response of the fabricated single-substrate CLC film depends on the chiral material doped into the CLC solution. The single-substrate ultrathin CLC film exhibits very high flexibility and robustness without performance reduction. The fabricated flexible single-substrate CLC film may pave the way for the development of novel technologies for thermoresponsive devices with changeable shapes and designs.
近年来，单基板柔性液晶（LC）器件因其能提供理想的形状、轻重量、柔韧性和可卷曲性而备受关注。在这项工作中，我们通过一种名为光增强分层法的简便方法制备了一种柔性单基板热响应型胆甾相液晶（CLC）薄膜。我们制备的单基板CLC薄膜由填充有CLC溶液的微米级聚合物容器组成。我们的结果表明，制备的单基板CLC薄膜的温度响应取决于掺杂到CLC溶液中的手性材料。该单基板超薄CLC薄膜表现出非常高的柔韧性和坚固性，且性能不降低。制备的柔性单基板CLC薄膜可能为开发具有可变形状和设计的热响应器件的新技术铺平道路。
