纳米科技的快速发展迫切需要对材料小尺度下的力学性能进行定量化测试与表征.将声学和原子力显微镜相结合的扫描探针声学显微技术(Atomic Force Acoustic Microscopy,AFAM)是近年来发展的一项定量化纳米力学测试方法,具有高分辨和无损的优势.论文围绕AFAM这一测试技术,首先详细论述了AFAM弹性力学性能和粘弹性力学性能定量化测试的基本原理以及两种成像模式;随后对AFAM方法研究相关的进展进行了分析和归纳;接着对AFAM在纤维增强复合材料、智能材料、生物材料、纳米材料和薄膜中的应用进展进行了综述;最后对AFAM进行了总结和展望.
The rapid development of nanotechnology urgently needs to quantitatively test and characterize the mechanical properties under the small scale of materials.Atomic Force Acoustic Microscopy (AFAM), which combines acoustic and atomic force microscopy, has been developed in recent years A quantitative nanomechanical test method has the advantages of high resolution and non-destructiveness.Firstly, based on the AFAM test technique, the basic principles of the quantitative testing of the elastic and viscoelastic mechanical properties of AFAM and the two imaging modes are discussed in detail. Then, the progress of the AFAM method research was analyzed and summarized. The progress of the application of AFAM in fiber-reinforced composites, smart materials, biomaterials, nanomaterials and films was reviewed. Finally, the AFAM was summarized and prospected.
