Abstract

This study aimed to address the environmental concerns associated with petrochemical-derived bisphenol-A, commonly used in epoxy resin synthesis, by developing an eco-friendly alternative utilizing bio-based ascorbic acid, or vitamin C. The epoxy compound was synthesized by leveraging the hydroxyl group inherent in ascorbic acid through a reaction with epichlorohydrin. Optimal curing conditions were determined via dynamic scan and isotherm analysis using Differential Scanning Calorimetry (DSC) for the newly synthesized epoxy resin in combination with isophorone diamine (IPDA) as the curing agent. The cured product, obtained under the identified optimal curing conditions, exhibited a soft hardened form with a tensile strength of 7.5 MPa and an elongation of 6%. These findings underscore the feasibility of synthesizing a commercially viable eco-friendly epoxy resin utilizing ascorbic acid, thus contributing to the ongoing pursuit of sustainable material alternatives. The results suggest potential scalability for mass production, emphasizing the significance of this approach in addressing the demand for environmentally friendly materials in various industrial applications.

抗坏血酸基环氧树脂的合成

本研究旨在利用生物基抗坏血酸或维生素 C 开发一种生态友好型替代品，从而解决环氧树脂合成中常用的石化衍生双酚 A 带来的环境问题。通过使用差示扫描量热仪（DSC）进行动态扫描和等温线分析，确定了新合成的环氧树脂与作为固化剂的异佛尔酮二胺（IPDA）的最佳固化条件。在确定的最佳固化条件下获得的固化产品呈现软硬化形态，抗拉强度为 7.5 兆帕，伸长率为 6%。这些发现强调了利用抗坏血酸合成商业上可行的生态友好型环氧树脂的可行性，从而推动了对可持续材料替代品的不断追求。研究结果表明该方法具有大规模生产的潜在可扩展性，强调了该方法在满足各种工业应用对环保材料需求方面的重要意义。
