摘　　要：文章模仿蛛网中包含不同结构的蛛丝,采用离心-静电纺丝法制备聚氨酯-聚对苯二甲酸乙二醇酯(PU-PET)复合纤维膜作为柔性基材,以多壁碳纳米管(MWCNTs)为导电介质,制备出兼具高弹性、高灵敏度的可拉伸复合纤维膜。不同纤维组成的复合纤维膜既能感知人体微小的动作变化,也可响应大幅度的肢体动作。经过一系列的性能测试表明,复合纤维膜断裂伸长率高、响应时间快、稳定性好、回复能力强、压力测试范围广,具有良好的抗氧化性能。这些优异的性能使得该复合纤维膜可以作为可穿戴器件监测人体不同部位的肢体动作,体现出分级响应能力。The article imitates spider webs with different structures and uses centrifugal-electrospinning to prepare polyurethane-polyethylene terephthalate(PU-PET)composite fiber membrane as the flexible substrate,with multi-walled carbon nanotubes(MWCNTs)as the conductive medium,to prepare stretchable composite fiber membrane with high elasticity and high sensitivity.The composite fiber membranes composed of different fibers can not only sense the tiny movement changes of human body,but also respond to large-scale body movements.After a series of performance tests,the composite fiber membranes had high elongation at break,fast response,good stability,strong recovery ability,wide test range of pressure and good oxidation resistance.These excellent performances enable such composite fiber membranes to be used as wearable devices to monitor the movements of different parts of the human body,reflecting graded response ability.
