This is a study on the development of carbon nanotube-based composite actuators using a new ionic liquid-doped electroactive ionic polymer. For scalable production purposes, a simple hot-pressing method was used. Carbon nanotube/ionic liquid-Nafion/carbon nanotube composite films were fabricated that exhibited a large output blocking force and a stable cycling life with low alternating voltage stimuli in air. Of particular interest and importance, a blocking force of 1.5 N was achieved at an applied voltage of 6 V. Operational durability was confirmed by testing in air for over 30 000 cycles (or 43 h). The superior actuation performance of the carbon nanotube/ionic liquid-Nafion/carbon nanotube composite, coupled with easy manufacturability, low driving voltage, and reliable operation, promises great potential for artificial muscle and biomimetic applications.
这是一项关于使用新型离子液体掺杂电活性离子聚合物开发基于碳纳米管的复合致动器的研究。出于可扩展生产的目的，采用了简单的热压法。制备了碳纳米管/离子液体-全氟磺酸/Nafion/碳纳米管复合薄膜，在空气中，这些薄膜在低交流电压刺激下表现出大的输出阻挡力和稳定的循环寿命。特别值得关注和重要的是，在 6 V 的外加电压下实现了 1.5 N 的阻挡力。通过在空气中进行超过 30000 次循环（或 43 小时）的测试，证实了其运行耐久性。碳纳米管/离子液体-全氟磺酸/Nafion/碳纳米管复合的优越致动性能，加上易于制造、低驱动电压和可靠的操作，有望在人造肌肉和仿生应用中具有巨大的潜力。
