摘要
文中采用静电纺丝法制备具有高弹性的热塑性聚氨酯(TPU)纳米纤维膜,并将其与银纳米线和碳纳米管复合,获得MWCNTs-AgNWs-TPU拉伸应变传感器,研究静电纺丝的接收速度和纳米纤维膜力学性能关系,以及拉伸应变传感器中银纳米线含量对传感器灵敏度、迟滞性的影响规律。最后应用传感器监测人体的运动姿态,该研究成果在健康监测的智能服装中具有广阔应用前景。
In this paper,the highly elastic thermoplastic polyurethane(TPU)nanofiber membrane was prepared by electrospinning,which was then compounded with silver nanowires(AgNWs)and carbon nanotubes(MWCNTs)to obtain a MWCNTs-AgNWs-TPU tensile strain sensor.The relationship between the receiving speed of electrospinning and the mechanical properties of the nanofiber membrane,as well as the influence of silver nanowire content in the tensile strain sensor on sensor sensitivity and hysteresis,were studied.Finally,the sensor was applied to monitor human motion posture.This research has broad application prospects in smart clothing,especially for health monitoring.
