Abstract

Shape memory epoxy resin (SMEP) offers high modulus and cost-effectiveness, making it suitable for aerospace components and smart building systems. This study reported a bio-based epoxy resin derived from gallic acid (bEP) with an optimized T_g of below 90°C and a flexural modulus above 2.54 GPa. The bEP demonstrated excellent shape memory properties, including a shape fixation ratio of 98% and a shape recovery ratio of 97%. Additionally, the composites prepared by the bEP showed excellent shape memory performance, achieving a 96% fixation ratio and a 95% recovery ratio, and can quickly recover 95% of their deformation within 30 s.
