An alternative magnetic field (AMF)-induced electrospun fibrous thermoresponsive composite actuator showing penetrable remote-control ability with fast response is shown here for the first time. The built-in heater of magnetothermal FeO nanoparticles in the actuator and the porous structure of the fibrous layer contribute to a fast actuation with a curvature of 0.4 mm in 2 s. The higher loading amount of the FeO nanoparticles and higher magnetic field strength result in a faster actuation. Interestingly, the composite actuator showed a similar actuation even when it was covered by a piece of Polytetrafluoroethylene (PTFE) film, which shows a penetrable remote-control ability.
本文首次展示了一种替代磁场（AMF）诱导的电纺纤维热响应复合致动器，其具有可穿透的远程控制能力且响应迅速。致动器中磁热FeO纳米颗粒的内置加热器和纤维层的多孔结构有助于实现快速致动，在2秒内曲率可达0.4毫米。FeO纳米颗粒的负载量越高以及磁场强度越高，致动速度就越快。有趣的是，即使复合致动器被一块聚四氟乙烯（PTFE）薄膜覆盖，它仍表现出类似的致动效果，这表明其具有可穿透的远程控制能力。
