摘要
碳纳米管因其拉曼光谱有明显的应力敏感性而被添加到聚合物材料中作为拉曼力学传感器。介绍了不同种类的碳纳米管及其聚集体对应力的不同响应,另外着重综述了碳纳米管拉曼传感器在检测基体受力情况以及在纤维增强材料界面性能方面的应用。同时也介绍了碳纳米管的功能化对于应力传感效果的影响。
Carbon nanotubes (CNTs)are added into polymers as Raman strain sensors because their Raman spectra are sensitive to strain. The different response of CNTs and their aggregates to stress are introduced. The ap- plications of CNT-based Raman strain sensors in characterizing the stress condition of the matrix and fiber reinforced materials are reviewed. In addition, the influences of functional CNTs on strain sensing are introduced.
