DNP enhanced solid-state NMR – A powerful tool to address the surface functionalization of cellulose/paper derived materials

Raw data of the publication. Abstract: This concept summarizes recent advances in development and application of DNP enhanced multinuclear solid-state NMR to study the molecular structure and surface functionalization of cellulose and paper-based materials. Moreover, a novel application is presented where DNP enhanced 13C and 15N solid-state NMR is used to identify structure moieties formed by cross-linking of hydroxypropyl cellulose. Given these two aspects of this concept-type of article, we thus combine both, a review on recent findings already published and unpublished recent data that complement the existing knowledge in the field of characterization of functional lignocellulosic materials by DNP enhanced solid-state NMR.本出版物的原始数据。 摘要： 本文总结了动态核极化（Dynamic Nuclear Polarization, DNP）增强型多核固体核磁共振（Multinuclear Solid-State Nuclear Magnetic Resonance, NMR）技术在纤维素与纸基材料的分子结构及表面功能化研究中的开发与应用进展。此外，本文还介绍了一项全新的应用场景：利用DNP增强的碳13（¹³C）与氮15（¹⁵N）固体核磁共振技术，鉴定羟丙基纤维素（Hydroxypropyl Cellulose, HPC）交联反应所形成的结构基团。鉴于本篇概念型文章涵盖上述两大研究方向，本文将二者有机融合：既系统梳理了该领域已发表的最新研究成果，又补充了尚未公开的前沿实验数据，以此完善基于DNP增强固体核磁共振技术表征功能化木质纤维素材料的相关知识体系。
