摘要：利用超顺排碳纳米管/高分子复合材料设计和制造了一种半透明的流量控制致动器.这种致动器能够像阀门一样工作,展示了一种新颖的不需要沉重的机械传动装置就可以实现流体流速控制的方法.通过电功率(或电压)能够实现对流体流速的精确控制,或者截断流体.透过半透明的致动器壁,能够清晰的观察到流量控制的过程.这个致动器具有低驱动电压(<6 V),良好的生物兼容性,良好的柔性和长的使用寿命(5000次循环以上)等优点,在仿生领域具有广阔的应用前景.

摘要：In recent years,actuators based on carbon nanotube（CNT） or graphene demonstrate great potential applications in the fields of artificial muscles,smart switches,robotics,and so *** electrothermal and photothermal bending actuators based on CNT/graphene and polymer composites show large bending actuations,which are superior to traditional thermaldriven ***,the influence of material parameters（thickness,temperature change,etc.） on the actuation performance needs to be further studied,because it is a critical point to the design and fabrication of high-performance *** this work,finite element analysis（EEA） is employed to simulate the actuation performance of CNT/polymer actuator,which has a bilayer *** main focus of this work is to design and to optimize material parameters by using computational *** simulation results show that each layer thickness of actuator has an important influence on the actuation deformation.A maximum curvature of 2.7 cm^（-1） is obtained by simulation,which is much larger than most of the actuator curvature reported in previous *** is more,larger temperature change and larger difference of coefficient of thermal expansion（CTE） between two layers will result in larger bending *** study is expected to provide valuable theoretical reference for the design and realization of CNT-based thermal actuator with ultra-large actuation performance.
