The development of sustainable epoxy vitrimers with outstanding mechanical strength and facile self-healing capabilities are great significance for prolonging the lifespan enhancing reliability electronic devices. In this study, we present a castor oil-derived vitrimer (ASB-ECO) featuring dual dynamic networks enabled by rationally designed ester-imine bonds an aromatic Schiff base-conjugated crosslinker architecture. This molecular design strategy effectively enhances properties vegetable oil-based endows them controllable under photothermal conversion. 1.0-ASB-ECO system demonstrates characteristics activation energy (Ea) 37.25 kJ/mol topological freezing transition temperature (Tv) 123.13 °C. material exhibits conversion efficiency (ηPT = 61.42%) can achieve rate 100% visible-light radiation. addition, displays dielectric constant (Dk) 5.54 loss tangent (Df) 0.025 at 106 Hz. study on biomass-based presents novel approach to developing materials, achieving combination high performance, sustainability, properties.
