Abstract

Bio-based aromatic diamines from vanillin substrate were successfully synthesized and characterized. These amines, i.e., methylated divanillylamine (MDVA) and 3,4-dimethoxydianiline (DMAN), were then tested as curing agents for the design of bio-based epoxy thermosets. The epoxy thermosets obtained from these novel vanillin-based amines exhibited promising thermomechanical properties in terms of glass transition temperature and char residue.

摘要

成功合成并表征了源自香草醛底物的生物基芳香二胺。然后，将这些胺，即甲基化双香草胺（MDVA）和3,4-二甲氧基二苯胺（DMAN），作为固化剂用于设计生物基环氧热固性材料。由这些新型香草醛基胺制得的环氧热固性材料在玻璃化转变温度和残炭方面表现出良好的热机械性能。
