振动光谱可以提供分子的振动信息,对于聚合物分子链的构象和链间的相互作用非常敏感。分子振动光谱成像作为一种原位无损检测技术,广泛应用于聚合物共混体系结晶、相态分布、界面扩散等性质的研究。本文综述了拉曼（Raman）光谱和红外（IR）光谱成像技术以及其衍生的具有高空间分辨率的红外-原子力联用技术（IR-AFM）、拉曼-原子力联用技术（Raman-AFM）以及针尖增强拉曼光谱技术（TERS）在聚合物共混体系研究中的最新应用进展,以探索并扩展振动光谱成像技术在高分子领域中的应用。

Vibrational Spectroscopy can provide molecular vibrational information and can be very sensitive to the conformation of polymer molecular chains and interaction between chains.Vibrational Spectroscopy Imaging as an in situ non-damage detection is widely applied to the study of polymer blend’s properties such as crystallization,distribution of phase state and interface diffusion.The present paper emphasized to summarize the headway of application research of polymer blend by imaging techniques of Raman Spectroscopy and Infrared Spectroscopy and their derivative techniques with high-space resolution ratio,such as the combination of Infrared Spectroscopy and Atomic Force Microscope(IR-AFM),the combination of Raman Spectroscopy and Atomic Force Microscope(Raman-AFM)and Tip-Enhanced Raman Spectroscopy(TERS),aiming to explore and expand the application of vibrational Spectroscopy imaging techniques in the polymer field.
