This study presents a sustainable approach to transform waste cooking oil (WCO) into multifunctional 3D-printable photocurable elastomer with integrated self-healing capabilities. A linear monomer, WCO-based methacrylate fatty acid ethyl ester (WMFAEE), was synthesized via sequential strategy of transesterification, epoxidation, and ring-opening esterification. By copolymerizing WMFAEE hydroxypropyl acrylate (HPA), novel developed, which could be amenable molding using an LCD light-curing 3D printer. The resulting WMFAEE-HPA exhibits exceptional mechanical flexibility (elongation at break: 645.09%) autonomous room-temperature properties, achieving 57.82% recovery elongation after 24 h 25 °C. Furthermore, the material demonstrates weldability (19.97% retained 12 80 °C) physical reprocessability (7.75% retention initial reprocessing). Additional functionalities include pressure-sensitive adhesion (interfacial toughness: 70.06 J/m2 on glass), thermally triggered shape memory behavior (fixed -25 °C reversible deformation/recovery ambient conditions), notable biodegradability (13.25% mass loss 45-day soil burial). Molecular simulations reveal that unique structure monomer enables dual mechanism room temperature without external stimuli: chain diffusion entanglement-driven gap closure, followed by hydrogen bond-mediated network reorganization. synergy between diffusion/entanglement dynamic bond reorganization allows system achieve balance integration. Moreover, integration these attributes highlights potential this WCO-derived for various possible printing applications, such as flexible electronics, adaptive robotics, environmentally benign adhesives, so on. It also establishes paradigm converting low-cost biowastes high-performance smart materials through precision molecular engineering.
