液晶分子自组装已成为提高质量传输和机械强度的一种有吸引力的策略。在这里，我们报道了基于将离子液体集成到纳米级一维通道中的光交联离子柱状液晶聚合物薄膜的低电压驱动驱动器。我们揭示了纳米通道对驱动器性能的影响。与相应的非晶态驱动器相比，纳米结构驱动器显示出更大的变形和产生力。由液体和各向异性刚性域组成的纳米分离的概念将为电致动器的设计开辟一条很有前途的途径。
Liquid-crystalline molecular self-assembly has become an attractive strategy to enhance mass transport and mechanical strength. Herein we report low-voltage-driven actuators based on photo-cross-linked ionic columnar liquid-crystalline polymer films integrating ionic liquids into nanoscale 1D channels. We have unveiled the effect of nanochannels on the actuator performance. The nanostructured actuator exhibits larger deformation and generated force compared with the corresponding amorphous actuator. The concept of nanosegregation consisting of liquid and anisotropic rigid domains will open up a promising pathway for electroactive actuator design.
