摘要
利用化学镀镍法制备一种柔性的导电棉纱电极,通过静电纺丝技术将纳米纤维包覆在镀镍棉纱表面作为介电层,设计得到了一种基于PU纳米纤维包芯纱的柔性电容式压力传感器。利用扫描电子显微镜对纳米纤维以及棉纤维的形貌进行表征,并通过数字源表和LCR电桥仪对纱线以及传感器的性能进行表征。结果表明：镀镍棉纱的电导率随着镀镍时间的延长而增大,当镀镍时间为8 h时,其电导率为25 S/cm,时间超过8 h后,电导率变化不大;镀镍后的棉纱显示出良好的力学性能;另外,基于纳米纤维包芯纱的压力传感器具有良好的传感性能,其灵敏度平均可达到0.375 N。
A flexible conductive cotton yarn electrode is prepared by electroless nickel plating. Nanofibers are coated on the surface of nickel-plated cotton yarns as a dielectric layer by electrospinning technology and a flexible capacitive pressure sensor based on PU nanofiber core-spun yarn is designed. The morphology of nanofibers and cotton fibers is characterized by SEM, and the properties of yarns and sensors are characterized by Digital Source-meter and LCR meter. The results show that cotton yarn has the highest conductivity. When the nickel plating time is 8h, the electrical conductivity of the nickel-plated is 25 S/cm. The Ni-coated cotton yarn shows good mechanical properties. In addition, the pressure sensor based on the nanofiber core-spun yarn has good sensing performance and its sensitivity could reach up to 0.375 N.
