Abstract

Abstract

En 中文
• Novel mixed-valence FeII/FeIII-Tar enables multifunctional EC based smart films. • An irreversible phase-transition mechanism enables high-fidelity visual signaling (ΔE > 29). • The bio-based films integrate ammonia sensing, antibacterial, and antioxidant activity. • Mechanical strength, UV-shielding, and barrier properties are significantly enhanced. • A feasible route is established to upgrade industrial crop biomass into high-value smart materials.
