摘　　要：液晶聚合物是一种环境刺激响应的智能形变材料,由这种智能材料构建的微型执行器可以将外界的环境刺激直接转换为机械运动,无需复杂的能量转换部件和机械传动结构,因此液晶聚合物微执行器在微型机器人、智能传输、生物医学设备等领域具有良好的应用前景。液晶聚合物的微加工存在两个技术难点:微纳尺度的器件成型和液晶取向。本文从如何解决这两个技术难点出发,介绍了近几年液晶聚合物的微纳加工方法以及相应功能器件的潜在应用领域。Liquid crystal polymers are environment-responsive materials capable of intelligent deformation.Microactuators constructed from these smart materials can directly convert environmental stimuli into mechanical motion without the need for complex energy conversion components or mechanical transmission structures.Consequently,liquid crystal polymer microactuators hold significant potential for applications in fields such as microrobotics,intelligent transport and biomedical devices.There are two primary technical challenges in the micromachining of liquid crystal polymer:the fabrication of micro/nanoscale devices and the alignment of liquid crystals.This paper reviews recent micro/nanofabrication methods for liquid crystal polymers and the potential application areas of the corresponding functional devices,focusing on how to address these two technical challenges.
