多刺激响应的三层结构致动器的制备与应用

Fabrication and application of multi-responsive tri-layer actuator

  • 摘要: 近年来,软体致动器因其能够响应外界条件的刺激而发生形变,在生物医疗、航空航天、智能仿生等领域备受关注。然而,外界环境的刺激往往复杂多变,多数致动器只能对单一刺激进行响应,这无疑增加了软体致动器的使用局限性。因此,有必要开发能响应多种外部条件变化的致动器。本文通过先后真空抽滤氧化石墨烯(GO)和MXene形成双层复合膜,再将聚丙烯(BOPP)胶带通过切割、粘贴和组装,开发了一种基于GO-MXene-BOPP胶带的三层结构致动器。该致动器能够在湿度和光照的刺激下快速发生形变,有效的将其他形式的能量转化为机械能。响应方式的灵活性使得该致动器在仿生机器人、可穿戴设备、微机电系统等领域具有广泛的应用前景。

     

    Abstract: In recent years, soft actuators have attracted much attention in the fields of biomedical, aerospace, and intelligent bionics because of their ability to deform in response to stimuli from external conditions. However, the stimuli of the external environment are often complex and variable, and most actuators can only respond to a single stimulus, which undoubtedly increases the limitations of soft actuators. Therefore, it is necessary to develop actuators that can respond to multiple stimuli in external conditions. In this paper, we developed a tri-layer structured actuator consisting of GO-MXene-BOPP tape by successively vacuum-filtering graphene oxide (GO) and MXene to form a bilayer composite film, and then cutting, pasting, and assembling polypropylene (BOPP) tape. The actuator is capable of undergoing rapid deformation in response to humidity and light stimuli, effectively converting other energy into mechanical energy. The flexibility of the response method enables the actuator to have a wide range of applications in the fields of bionic robotics, wearable devices, and microelectromechanical systems.
