Abstract

Increasing demand for bio-based epoxy thermoset alternatives has risen in the last few years. Epoxidized vegetable oils (EVO) have attracted significant attention due to their bio-based, unharmful nature and high availability. This study proposes a fully bio-based epoxy thermoset based on epoxidized linseed oil (ELO) and tannic acid (TA). TA allows, with its high degree of functionality and aromatic structure as a curing agent for ELO, to create a fully bio-based polymer network with a high glass transition temperature (Tg), high stiffness, and high strength. A maximum Tg of 146 °C, a flexural modulus of 2986 MPa, and flexural strength of 72 MPa are obtained. The strong material properties of the TA/ELO thermoset expose its potential as a bio-based substitute for petrochemical-based epoxy resins for high-performance applications.

基于环氧化亚麻籽油和单宁酸的全生物基环氧热固性树脂
在过去几年中,对生物基环氧热固性替代品的需求不断增加。环氧化植物油(EVO)因其生物基性、无害性和高可用性而受到广泛关注。本研究提出了一种以环氧化亚麻籽油(ELO)和单宁酸(TA)为原料的全生物基环氧热固性树脂。作为ELO的固化剂,TA具有高度的功能性和芳香结构,可以创建具有高玻璃化转变温度(Tg)、高刚度和高强度的全生物基聚合物网络。最大Tg为146℃,抗弯模量为2986 MPa,抗弯强度为72 MPa。TA/ELO热固性材料的强大材料性能显示了其作为石化基环氧树脂高性能应用的生物基替代品的潜力。
