摘要：
通过精准调控过硫酸铵、亚甲基双丙烯酰胺、二甲基丙烯酰胺和聚环氧乙烷的浓度，研究人员制备出了一种具备卓越拉伸性能的水凝胶，其拉伸长度可达原始长度的260倍。本研究旨在借助人工智能预测系统，探索潜在的反应机制，以阐明支撑这一独特现象的分子结构。人工智能预测器提出了一种连接两种聚合物的新方法：在随机断链后，形成由线性链相互连接的网络结构。这种全新的构型催生了一类独特的水凝胶，本文将其命名为“Span Network（跨度网络）”。此外，研究还采用傅里叶变换红外光谱（FTIR）对可能参与该反应机制的官能团进行了探究，证实了聚环氧乙烷（PEO）断链产生的大量羟基端基，与水凝胶网络上形成的羧基之间发生了酯化反应。
英文摘要：
The deliberate manipulation of ammonium persulfate, methylenebisacrylamide, dimethyleacrylamide, and polyethylene oxide concentrations resulted in the development of a hydrogel with an exceptional stretchability, capable of extending up to 260 times its original length. This study aims to elucidate the molecular architecture underlying this unique phenomenon by exploring potential reaction mechanisms, facilitated by an artificial intelligence prediction system. Artificial intelligence predictor introduces a novel approach to interlinking two polymers, involving the formation of networks interconnected with linear chains following random chain scission. This novel configuration leads to the emergence of a distinct type of hydrogel, herein referred to as a "Span Network." Additionally, Fourier-transform infrared spectroscopy (FTIR) is used to investigate functional groups that may be implicated in the proposed mechanism, with ester formation confirmed among numerous hydroxyl end groups obtained from chain scission of PEO and carboxyl groups formed on hydrogel networks.
