Abstract

Flexible sensors with a high sensitivity and wide-frequency response are essential for structural health monitoring (SHM) while they are attached. Here, carbon nanotube (CNT) films doped with various PVA fractions (CNT/PVA) and ZnO nanowires (nano-ZnO) on zinc sheets were first fabricated by functionalized self-assembly and hydrothermal synthesis processes. A CNT/PVA/nano-ZnO flexible composite (CNT/PVA/ZnO) sandwiched with a zinc wafer was then prepared by the spin-coating method. The piezoresistive and/or piezoelectric capabilities of the CNT/PVA/ZnO composite were comprehensively investigated under cyclic bending and impact loading after it was firmly adhered to a substrate (polypropylene sheet or mortar plate). The results show that the piezoresistive sensitivity and linear stability of the CNT/PVA films doped with 20%, 50%, and 100% PVA during bending are 5.47%/mm, 11.082%/mm, and 11.95%/mm and 2.3%, 3.42%, and 4.78%, respectively. The piezoelectric sensitivity, linear stability, and response accuracy of the CNT/PVA/ZnO composite under impulse loading are 4.87 mV/lbf, 3.42%, and 1.496 ms, respectively. These merits support the use of CNT/PVA/ZnO as a piezoresistive and/or piezoelectric compound sensor to monitor the static/dynamic loads on concrete structures while it is attached.

摘要

具有高灵敏度和宽频率响应的柔性传感器对于附着时的结构健康监测（SHM）至关重要。在此，首先通过功能化自组装和水热合成工艺在锌片上制备了掺杂不同聚乙烯醇（PVA）含量的碳纳米管（CNT）薄膜（CNT/PVA）和氧化锌纳米线（纳米ZnO）。然后通过旋涂法制备了夹有锌片的CNT/PVA/纳米ZnO柔性复合材料（CNT/PVA/ZnO）。在将CNT/PVA/ZnO复合材料牢固地粘附到基材（聚丙烯片或砂浆板）上之后，对其在循环弯曲和冲击载荷下的压阻和/或压电性能进行了全面研究。结果表明，掺杂20%、50%和100%PVA的CNT/PVA薄膜在弯曲过程中的压阻灵敏度和线性稳定性分别为5.47%/mm、11.082%/mm和11.95%/mm以及2.3%、3.42%和4.78%。CNT/PVA/ZnO复合材料在脉冲载荷下的压电灵敏度、线性稳定性和响应精度分别为4.87 mV/lbf、3.42%和1.496 ms。这些优点支持将CNT/PVA/ZnO用作压阻和/或压电复合传感器，以在附着时监测混凝土结构上的静态/动态载荷。
