摘要

摘要: 碳纳米管薄膜可作为应变传感器用于结构损伤的健康监测。采用机械搅拌、超声处理和高速离心等分散工艺将多壁碳纳米管单分散后,通过真空吸滤法制备碳纳米管薄膜。对碳纳米管薄膜传感器进行了深入的研究,设计了一种高灵敏度的碳纳管薄膜应变传感器,与结构基体一体成型。弯曲应变传感实验表明碳纳米管薄膜传感器在不同的应变范围、不同的循环次数、不同的温度范围等条件下都具有良好的应变传感特性。结果表明碳纳米管薄膜传感器灵敏度较高,灵敏度系数为188.31(0~22 500 με),且具有较好的应变传感可逆性和可重复性。

Abstract: Due to the aviation accident caused by structure deformation occurring frequently, the health monitoring of aircraft's structure has become one of the effective means of prevention. Carbon nanotubes thin film can be used as strain sensor for health monitoring of structure damage. The dispersion techniques such as mechanical agitation, ultrasonic processing and centrifugal processing had been combined for realizing the monodispersion of carbon nanotubes in aqueous medium. Carbon nanotubes thin films was fabricated with monodispersion solution of muti-walled carbon nanotubes through vacuum filtration method for strain sensing. We designed a carbon nanotubes thin film sensor which was formed with matrix of structure for strain sensing. Bending strain sensing experiment shows that carbon nanotubes thin film sensors in different strain ranges and different cycling times and different temperature conditions has good strain sensing characteristic. The response and sensitivity to strain of carbon nanotubes thin film were investigated. The sensing mechanism of carbon nanotubes film shows that the resistance of the carbon nanotubes thin film increases with the increase of strain. The results indicate that carbon nanotubes thin film sensor has a very high strain sensitivity in the strain range of 0-22 500 με with gauge factor of 188.31 and has excellent reversible and repetition characteristics.
