Abstract

Abstract

En 中文
• Bio-based benzoxazines from vanillin, daidzein and naringenin via green synthesis. • Monomer functionality governs thermal, mechanical and moisture-resistance properties. • Daidzein-based thermoset achieves highest Tg (278 °C) and thermal stability. • Naringenin system yields highest hardness (Shore D 93) and lowest water uptake. • Vanillin-based polymer shows best tensile strength for composite matrix applications.
