原子力显微镜在高分子物理实验教学中的应用实例

Application Examples of Atomic Force Microscope in PolymerPhysics Experiment Teaching

原子力显微镜广泛应用到高分子研究的各个方面,操作简单,分辨率高,可以定性定量的表征材料表面的微观形貌及其物理性质。以尼龙6纤维增强橡胶基底为例,将原子力显微镜运用于高分子物理实验教学中,使用定量纳米机械力测量模式可以更好地研究纤维与橡胶基底的结合情况,从而阐明纤维增强橡胶的原理。该实验的加入可以提高学生的学习兴趣,加深对所学知识的理解,提高动手能力,培养更好的科研能力。

Atomic force microscopy is widely used in many aspects of polymer research.It is easy to operate and has high resolution.It can qualitatively and quantitatively characterize the microscopic morphology and physical properties of the material surface.Taking nylon 6 fiber-reinforced rubber substrate as an example,the atomic force microscope is used in polymer physics experiment teaching and the quantitative nano-mechanical force measurement mode can better study the combination of fiber and rubber substrate,thereby improving the principle of fiber-reinforced rubber.Taking this experiment as an example,scientific research enhances students'interest in learning,deepens their understanding of what they have learned,improves practical skills,and cultivates better scientific research capabilities.
