显微红外光谱技术兼具测试速度快、样品无损、可视化、微区化、精细化、灵敏化、图谱合一化等优点,是传统的红外光谱技术所无法比拟的,目前在高分子材料、侦探、法医、化学化工、医学、电子等领域已得到广泛的应用。本文介绍了红外光谱的原理,红外光谱技术及显微红外光谱技术的发展,概述了显微红外光谱技术在高分子多层膜成分鉴定、高分子老化机制、高分子相容性、高分子纤维、高分子结晶性及高分子溶解性等领域研究中的应用。
Microscopic infrared spectroscopy combines the advantages of fast test speed, non-destructive sample, visualization, micro-localization, refinement, sensitization and combination of spectra, which is unmatched by traditional infrared spectroscopy. Currently, Detectives, forensics, chemical industry, medicine, electronics and other fields have been widely used. In this paper, the principle of infrared spectroscopy, the development of infrared spectroscopy and microscopic infrared spectroscopy are introduced. The application of microscopic infrared spectroscopy in the identification of polymer multilayer films, polymer aging mechanism, polymer compatibility, , Polymer crystallinity and polymer solubility in areas such as research applications.
