Abstract

Epoxy resin thermosets (ERTs) are an important class of polymeric materials. However, owing to their highly cross-linked nature, they suffer from poor recyclability, which contributes to an unacceptable level of environmental pollution. There is a clear need for the design of inherently recyclable ERTs that are based on renewable resources. We present the synthesis and closed-loop recycling of a fully lignocellulose-derivable epoxy resin (DGF/MBCA), prepared from dimethyl ester of 2,5-furandicarboxylic acid (DMFD), 4,4′-methylenebis(cyclohexylamine) (MBCA), and glycidol, which displays excellent thermomechanical properties (a glass transition temperature of 170°C, and a storage modulus at 25°C of 1.2 gigapascals). Notably, the material undergoes methanolysis in the absence of any catalyst, regenerating 90% of the original DMFD. The diamine MBCA and glycidol can subsequently be reformed by acetolysis. Application and recycling of DGF/MBCA in glass and plant fiber composites are demonstrated.

通过甲醇分解实现生物质衍生环氧胺热固性物质的闭环可回收性
环氧树脂热固性塑料(ERT)是一类重要的聚合物材料。然而,由于其高度交联的性质,它们的可回收性很差,造成了不可接受的环境污染。显然,我们需要设计出基于可再生资源的固有可回收 ERT。我们介绍了由 2,5-呋喃二甲酸二甲酯(DMFD)、4,4′-亚甲基双(环己基胺)(MBCA)和缩水甘油制备的可完全衍生木质纤维素的环氧树脂(DGF/MBCA)的合成和闭环回收,该树脂具有优异的热机械性能(玻璃化转变温度为 170°C,25°C 时的储存模量为 1.2 千兆帕)。值得注意的是,这种材料在没有任何催化剂的情况下也能进行甲醇分解,再生出 90% 的原始 DMFD。随后,二胺 MBCA 和缩水甘油可通过乙醇分解进行重整。演示了 DGF/MBCA 在玻璃纤维和植物纤维复合材料中的应用和回收。

期刊介绍: Science is a leading outlet for scientific news, commentary, and cutting-edge research. Through its print and online incarnations, Science reaches an estimated worldwide readership of more than one million. Science’s authorship is global too, and its articles consistently rank among the world's most cited research. Science serves as a forum for discussion of important issues related to the advancement of science by publishing material on which a consensus has been reached as well as including the presentation of minority or conflicting points of view. Accordingly, all articles published in Science—including editorials, news and comment, and book reviews—are signed and reflect the individual views of the authors and not official points of view adopted by AAAS or the institutions with which the authors are affiliated. Science seeks to publish those papers that are most influential in their fields or across fields and that will significantly advance scientific understanding. Selected papers should present novel and broadly important data, syntheses, or concepts. They should merit recognition by the wider scientific community and general public provided by publication in Science, beyond that provided by specialty journals. Science welcomes submissions from all fields of science and from any source. The editors are committed to the prompt evaluation and publication of submitted papers while upholding high standards that support reproducibility of published research. Science is published weekly; selected papers are published online ahead of print.
