摘要: 以电纺聚氨酯(PU)纤维膜为基底,用滴涂聚苯胺(PANI)的方法,制备了具有不对称结构的PANI/PU双层薄膜气致驱动器。研究发现,在氯化氢气体的诱导下,该PANI/PU双层膜表现出弯曲-恢复的形变行为,这与氯化氢对聚苯胺的吸/脱附及掺杂/脱掺杂有关。此外,对驱动器承重的研究表明,PANI/PU双层人工智能肌肉可承重其自身重量的9倍以上,显示出良好的承重能力。该气致驱动器制备方法简单,其气体响应的驱动行为易于操作,具有重要的技术应用前景。

Abstract: Polyaniline/polyurethane (PANI/PU) bilayer actuators are fabricated using PANI nanofibers as active material and electrospun polyurethane (PU) fibers as substrate. It is found that the PANI/PU bilayer actuators undergo bending-recovery movement induced by hydrochloride vapor. The deformation mechanism of the bilayer actuators might result from asymmetric volume expansion/contraction because of doping/dedoping and sorption/desorption of chemical vapors. Moreover, the PANI/PU bilayer actuator can carry over 9 times its own weight due to the high toughness of PU fibers, displaying the well load-bearing capacity. Because the PANI/PU actuator is ultra-lightweight, low cost and simple operation, it is advantageous for practical applications in the future.
