Abstract

Owing to its low-cost maintenance and easy adaptability, low-field NMR (LF-NMR), which is developed based on permanent magnets, has attracted increasing attention in recent decades. It shows great potential for fundamental research as well as quality assessment and control in the industry. In this review, we first present the key hardware features of LF-NMR, including magnets, radiofrequency (RF) coils, spectrometers, and hyphenated units. Subsequently, commonly used pulse sequences and basic theoretical treatments are summarized. The applications of LF-NMR in polymer science are discussed in detail, including chain dynamics, polymer networks, and hierarchical morphologies. The multiphase and multicomponent features of polymers make polymer science a suitable area for developing new LF-NMR techniques. A personal perspective on the further development of LF-NMR is also presented.

聚合物科学的低场核磁共振

基于永磁体的低场核磁共振技术（low-field NMR，简称fl -NMR）由于其维护成本低、适应性强等优点，近年来受到越来越多的关注。它在基础研究和行业质量评估和控制方面显示出巨大的潜力。在这篇综述中，我们首先介绍了LF-NMR的主要硬件特征，包括磁体，射频（RF）线圈，光谱仪和连字符单元。总结了常用的脉冲序列和基本的理论处理方法。详细讨论了LF-NMR在聚合物科学中的应用，包括链动力学、聚合物网络和层次形貌。聚合物的多相和多组分特性使聚合物科学成为开发新型LF-NMR技术的合适领域。并对LF-NMR的进一步发展提出了个人的看法。

期刊介绍： Giant is an interdisciplinary title focusing on fundamental and applied macromolecular science spanning all chemistry, physics, biology, and materials aspects of the field in the broadest sense. Key areas covered include macromolecular chemistry, supramolecular assembly, multiscale and multifunctional materials, organic-inorganic hybrid materials, biophysics, biomimetics and surface science. Core topics range from developments in synthesis, characterisation and assembly towards creating uniformly sized precision macromolecules with tailored properties, to the design and assembly of nanostructured materials in multiple dimensions, and further to the study of smart or living designer materials with tuneable multiscale properties.
