Abstract

Macroscopic assembly has been explored as a strategy to construct appealing materials. Yet, an open question remains: does macroscopic assembly always occur one by one? In this study, a new kind of silk-based hydrogel was developed through incorporating lignin-related compounds via 1-ethyl-3-(3-pyl)-carbodiimide/N-hydroxysuccinimide (EDC/NHS)-mediated coupling chemistry. Thanks to the hydrogen-bond, hydrophobic, and π-π interactions, the hydrogels possessed the capability of adhesive and macroscopic assembly, which could be further tuned by introducing iron ions, as Fe³⁺ can form coordination bonds with lignin. Examination of the three-body macroscopic assembly behavior of the silk/lignin-based hydrogels was conducted as an approach towards answering the above question. Under the experimental conditions tested in this study, the answer is yes. However, it would be premature to draw a definitive conclusion on this question. This study aims to highlight this issue and stimulate further interest and research in diverse macroscopic assembly systems.

丝/木质素基黏附水凝胶的宏观组装行为：基本宏观组装。

宏观组装是构建吸引人的材料的一种策略。然而，一个悬而未决的问题仍然存在：宏观组装总是一个接一个地发生吗？本研究通过1-乙基-3-(3-pyl)-碳二亚胺/ n-羟基琥珀酰亚胺（EDC/NHS）介导的偶联化学，将木质素相关化合物掺入丝基水凝胶中，制备了一种新型丝基水凝胶。由于氢键、疏水和π-π相互作用，水凝胶具有粘附和宏观组装的能力，并且可以通过引入铁离子进一步调整，因为Fe3+可以与木质素形成配位键。通过对蚕丝/木质素基水凝胶的三体宏观组装行为的研究来回答上述问题。在本研究测试的实验条件下，答案是肯定的。但是，对这个问题作出明确的结论还为时过早。本研究旨在突出这一问题，并激发人们对不同宏观装配系统的进一步兴趣和研究。

期刊介绍： Materials Horizons is a leading journal in materials science that focuses on publishing exceptionally high-quality and innovative research. The journal prioritizes original research that introduces new concepts or ways of thinking, rather than solely reporting technological advancements. However, groundbreaking articles featuring record-breaking material performance may also be published. To be considered for publication, the work must be of significant interest to our community-spanning readership. Starting from 2021, all articles published in Materials Horizons will be indexed in MEDLINE©. The journal publishes various types of articles, including Communications, Reviews, Opinion pieces, Focus articles, and Comments. It serves as a core journal for researchers from academia, government, and industry across all areas of materials research. Materials Horizons is a Transformative Journal and compliant with Plan S. It has an impact factor of 13.3 and is indexed in MEDLINE.
