与超顺排碳纳米管薄膜相互浸润的高分子具有均匀的导电性、良好的生物兼容性、合适的力学性能,它在电热型致动器研究领域具有广阔的应用前景。在本文中,首先利用这种具有双层结构的复合材料制作了一个简单的U型小器件来展示电热致动器的工作原理,在电热的作用下该小器件能够产生730°的卷曲。其次,本文介绍了一种具有旋转结构手臂状的致动器(人工手臂)。在低电场(小于41 V or 500 V/m)的作用下,该人工手臂能够产生大的形变(大于700°旋转,49.2%的长度收缩和26.4%的直径收缩)。所制作的人工手臂和U型小器件能够受电压(或电功率)的精确控制。该人工手臂能够握起4 g(自重的26倍)的重物,展示了一种新的抓取物体的方式,在仿生领域具有良好的应用前景。
The polymer with the super-aligned carbon nanotube film infiltrated with each other has uniform conductivity, good biocompatibility and suitable mechanical properties, and has broad application prospects in the field of electrothermal actuators. In this paper, a simple U-shaped device is firstly fabricated by using the composite material with a double-layer structure to demonstrate the working principle of the electro-thermal actuator, which can generate a curl of 730 ° under the action of electric heat. Second, this article describes an arm-like actuator (artificial arm) with a rotating structure. The artificial arm is capable of producing large deformations (greater than 700 ° rotation, 49.2% length contraction and 26.4% diameter contraction) at low electric fields (less than 41 V or 500 V / m). The fabricated artificial arms and U-shaped devices can be precisely controlled by voltage (or electric power). The artificial arm holds up to 4 g (26 times its own weight) of weight, showing a new way of grasping objects with good prospects in biomimetic applications.
