Abstract

The curing agent is an essential component in the epoxy resin (EP) system, while the rational construction of the curing agent is highly desired for practical applications. In this study, a novel curing agent was developed using Zeolitic imidazolate framework-8 (ZIF-8) and 1-ethyl-3-methylimidazolium acetate ([Emim][Ac]). [Emim][Ac]@ZIF-8 serves as both a functional filler and a curing agent for preparing [Emim][Ac]@ZIF-8/EP. The curing behavior of [Emim][Ac]@ZIF-8/EP was investigated through differential scanning calorimetry (DSC) characterizations. Notably, during the curing reaction of the epoxy resin, [Emim][Ac]@ZIF-8 exhibited delayed kinetic behavior compared to pure [Emim][Ac]. Furthermore, the impact of the loading amount of [Emim][Ac] and the dosage of [Emim][Ac]@ZIF-8 on the curing temperature of the system was explored. Finally, the curing kinetics of epoxy resin (E-51) in both [Emim][Ac]@ZIF-8 and [Emim][Ac] were analyzed using DSC at different heating rates. This work provides an insightful guidance for the construction of effective fillers for the preparation of epoxy composites.

基于[Emim][Ac]/唑族咪唑酸框架复合材料的新型环氧树脂固化剂的合成与表征

固化剂是环氧树脂（EP）体系中不可或缺的成分，而在实际应用中，对固化剂结构的合理性要求很高。本研究利用沸石咪唑酸框架-8（ZIF-8）和 1-乙基-3-甲基咪唑鎓醋酸盐（[Emim][Ac]）开发了一种新型固化剂。在制备 [Emim][Ac]@ZIF-8/EP 时，[Emim][Ac]@ZIF-8 既是功能填料，又是固化剂。通过差示扫描量热法（DSC）表征研究了[Emim][Ac]@ZIF-8/EP 的固化行为。值得注意的是，在环氧树脂的固化反应过程中，[Emim][Ac]@ZIF-8 与纯[Emim][Ac]相比表现出延迟的动力学行为。此外，还探讨了[Emim][Ac]的负载量和[Emim][Ac]@ZIF-8 的用量对体系固化温度的影响。最后，使用 DSC 分析了不同加热速率下环氧树脂（E-51）在 [Emim][Ac]@ZIF-8 和 [Emim][Ac] 中的固化动力学。这项工作为构建制备环氧树脂复合材料的有效填料提供了深刻的指导。

期刊介绍： Russian Journal of General Chemistry is a journal that covers many problems that are of general interest to the whole community of chemists. The journal is the successor to Russia’s first chemical journal, Zhurnal Russkogo Khimicheskogo Obshchestva (Journal of the Russian Chemical Society ) founded in 1869 to cover all aspects of chemistry. Now the journal is focused on the interdisciplinary areas of chemistry (organometallics, organometalloids, organoinorganic complexes, mechanochemistry, nanochemistry, etc.), new achievements and long-term results in the field. The journal publishes reviews, current scientific papers, letters to the editor, and discussion papers.
