ABSTRACT To regulate the mechanical and thermal properties of epoxy resin (Ep) achieve controllability its shape memory response, this work involves physical modification Ep using polyethylene glycol (PEG), leading to development Ep/PEG (EpP) films. As PEG content increases, EpP gradually transitions from rigid flexible. Notably, breaking strain EpP‐30 with 30% increased by 27.19% compared EpP‐0 without PEG. The are also modulated content, glass transition temperature (T g ) decreasing as increases. Specifically, T is reduced 33.44°C EpP‐0. developed exhibits excellent performance, response can be adjusted through content. Furthermore, demonstrates dual triple‐shape functions. In summary, achieves regulation PEG, successfully developing a controllable temperatures capabilities for triple responses.

This work focuses on biobased reactive diluents' synthesis, continuing with optimized oil-based resin precursor production. Our approach introduces vanillin methacrylate (VanMMA), cinnamyl (CinMMA), and vanillyl dimethacrylate (VanDiMMA) synthesis using methacrylic anhydride. The introduced involves an innovative available catalyst, potassium acetate, which possesses much suitable potential compared the usually used 4-dimethylaminopyridine (DMAP). Moreover, we separated formed secondary product, acid (MA), it to modify rapeseed oil prepare a curable thermoset. All synthesized products were structurally verified via complex cross-analysis (NMR, ESI-MS, FTIR). systems mixed form multicomponent mixture appropriate for stereolithography (SLA) 3D printing. It was found that VanDiMMA exhibited comparable diluting properties commercially compound, isobornyl (IBOMA), while achieving better mechanical, thermo-mechanical, thermal than IBOMA. VanDiMMA-containing SLA reached tensile strength of 12.7 ± 0.3 MPa, flexural 16.8 0.4 storage modulus 570 MPa at 30 °C, glass-transition temperature 83.7 heat-resistant index 169.5 °C.
