摘要
随着原位系统研究的进步以及灵敏度的提高,原位核磁共振在高分子材料领域的应用越来越广泛.原位液体核磁共振具有分析速度快、适用范围宽、无损检测、无需标样等特点,多用于表征聚合反应动力学及反应机理.除此之外,它还可以通过与其他仪器进行联用、匹配适用的探头等手段分离并解析未知物的化学结构.因此,原位液体核磁共振波谱技术将成为高分子科学研究领域不可或缺的通用工具.
With the shift toward the study of systems in operando and with increasing sensitivity,in operando nuclear magnetic resonance(NMR)is becoming more and more widely used in the field of polymer materials.In operando liquid state NMR provide mechanistic and kinetic information on polymerization reactions with the needless for stable labeling isotope,fast analysis,wide application range and maintaining intact samples.In addition,using the hyphenation of other characterization methods with in operando NMR spectroscopy is one of the most powerful methods for the separation and structural elucidation of unknown compounds and molecular compositions of mixtures by designing a suitable probe.In operando NMR spectroscopy will remain an indispensable and versatility tool in macromolecular science for years to come.
