标题： Understanding Polymer-Colloid Gels: A Solvent Perspective Using Low-Field NMR

摘要： 本工作强调了低场核磁共振弛豫谱学在研究胶体-聚合物水凝胶中的重要性，通过探测从$\rm 10^{\circ}C$到$\rm 80^{\circ}C$的广泛配方中的水动力学来实现。 通过研究横向弛豫时间$T_2$的温度依赖性，我们证明了NMR响应与水凝胶的流变行为之间存在明确的联系。 特别是，我们表明针对溶剂的NMR弛豫谱学能够提供关于水凝胶微观结构的可靠见解，并能够检测相变和老化过程。 我们的研究结果表明，这种以溶剂为重点的技术可以极大地促进软物质领域的发展，在凝胶研究中补充其他实验方法。 显示英文摘要

摘要： The present work emphasizes the relevance of low-field NMR relaxometry to investigate colloid-polymer hydrogels by probing water dynamics across a wide range of formulations between $\rm 10^{\circ}C$ and $\rm 80^{\circ}C$. By examining the temperature dependence of the transverse relaxation time $T_2$, we demonstrate a clear link between the NMR response and the rheological behavior of the hydrogels. In particular, we show that NMR relaxometry targeting the solvent provides reliable insights into the hydrogel microstructure and allows the detection of phase transitions and aging processes. Our findings suggest that this solvent-focused technique could greatly benefit the soft matter community, complementing other experimental methods in the study of gels.
