Liquid crystal polymers are a special class of soft materials that can change their shape in response to numerous stimuli such as light, heat, electric field, and chemicals. The ability to tailor the deformed shape by tuning the alignment of mesogens across the film has enabled the researchers to generate unique motions from these liquid crystal polymer thin films. Simulating such motions might allow us to understand the underlying mechanisms better and could lead to novel designs. In this paper, we analyze the kinematics of the light-driven rolling motion of wheels fabricated with azobenzene-doped glassy liquid crystal networks through a one-way coupled transient photo-mechanical model. The influence of the isomerization parameters and the alignment of mesogens through the thickness on the kinematics of the wheel is presented. The developed model is further used to assess the feasibility of a light-actuated four-wheeled cart with wheels made of azobenzene-doped liquid crystal network thin films.

一种光驱动液晶聚合物无电机微型推车的数值分析与设计

液晶聚合物是一类特殊的软材料,可以根据光、热、电场和化学物质等多种刺激改变其形状。通过调整薄膜上介晶的排列来调整变形形状的能力使研究人员能够从这些液晶聚合物薄膜中产生独特的运动。模拟这样的运动可能会让我们更好地理解潜在的机制,并可能导致新颖的设计。在本文中,我们通过单向耦合瞬态光机械模型分析了由掺杂偶氮苯的玻璃液晶网络制成的车轮的光驱动滚动运动的运动学。介绍了异构化参数和介晶通过厚度排列对轮运动学的影响。
