摘要

本研究研究了由糠胺和阿威酸衍生的环氧单体与生物基羧酸PRIPOL 1017合成的生物基热固性材料的热固化行为和热机械性能。该合成涉及使用糠酰胺和阿魏酸来开发环氧单体，增强了这些生物基平台分子的潜在用途。对热固化过程进行了全面的研究，以了解所涉及的动力学和机制。采用差示扫描量热法（DSC）、傅里叶变换红外光谱法（FTIR）和流变学方法监测固化反应的进展，并对固化过程中发生的化学变化进行表征。研究了固化温度、固化时间等参数对固化网络固化动力学的影响。此外，还对固化后的环氧树脂网络的热机械性能进行了综合评价。通过动态力学分析（DMA）和DSC来评估单体的化学结构与固化网络的热力学性能之间的关系。这为了解生物基热固性材料的结构-性能关系提供了有价值的见解。总的来说，这项研究突出了阿魏酸二氧基和二缩水甘油酯糠胺在可持续热固性材料开发方面的潜力。

Exploiting epoxy-based monomers from biobased ferulic acid and furfuryl amine for a new set of bio-derived materials

This study investigates the thermal curing behavior and thermo-mechanical properties of bio-based thermosets generated from epoxy monomers derived from furfuryl amine and ferulic acid, in conjunction with the bio-based carboxylic acid, PRIPOL 1017. The synthesis involves use of furfuryl amine and ferulic acid to develop epoxy monomers, enhancing the potential use of these bio-based platform molecules. The thermal curing process was thoroughly examined to understand the kinetics and mechanisms involved. Differential scanning calorimetry (DSC) and Fourier-transform infrared spectroscopy (FTIR) and rheology were employed to monitor the progress of the curing reaction and to characterize the chemical changes occurring during the process. The influence of curing parameters such as temperature and time on the curing kinetics of the cured networks was systematically investigated. Furthermore, the thermo-mechanical properties of the cured epoxy networks were comprehensively evaluated. Dynamic mechanical analysis (DMA) and DSC were conducted to assess the relationship between the chemical structure of the monomers and the resulting thermo-mechanical properties of the cured networks. This provided a valuable insight into structure-property relationships of the bio-based thermosetting materials. Overall, this study highlights the potential of ferulic acid diepoxy and diglycidyl furfurylamine for the development of sustainable thermosetting materials.

期刊介绍： Reactive & Functional Polymers provides a forum to disseminate original ideas, concepts and developments in the science and technology of polymers with functional groups, which impart specific chemical reactivity or physical, chemical, structural, biological, and pharmacological functionality. The scope covers organic polymers, acting for instance as reagents, catalysts, templates, ion-exchangers, selective sorbents, chelating or antimicrobial agents, drug carriers, sensors, membranes, and hydrogels. This also includes reactive cross-linkable prepolymers and high-performance thermosetting polymers, natural or degradable polymers, conducting polymers, and porous polymers. Original research articles must contain thorough molecular and material characterization data on synthesis of the above polymers in combination with their applications. Applications include but are not limited to catalysis, water or effluent treatment, separations and recovery, electronics and information storage, energy conversion, encapsulation, or adhesion.
