传统NMR技术需将被检测物体置于高频超导磁铁中心,其应用范围受到了很大限制。近年来出现了一种新型便携式核磁共振通用表面探测仪(NMR-MOUSE),它可以放置于被检测物表面进行在线分析,灵敏地检测出材料的变化,可在相关领域用于评估材料性能,并预测材料的使用寿命。文中主要介绍NMR-MOUSE的基本原理,并着重讨论其在非均相橡胶和塑料高分子聚合物表征领域中的应用情况。 Traditional NMR technology needs to be tested objects placed in the center of high-frequency superconducting magnet, its application has been greatly restricted. In recent years, a new type of portable nuclear magnetic resonance surface detector (NMR-MOUSE), which can be placed on the surface of the analyte on-line analysis, the sensitive detection of material changes can be used in the relevant field to evaluate the material properties, And predict the useful life of the material. This paper mainly introduces the basic principle of NMR-MOUSE, and focuses on its application in the field of heterogeneous rubber and plastic polymer characterization.
