Levoglucosenone to 3D-printed green materials: synthesizing sustainable and tunable monomers for eco-friendly photo-curing

Résumé

3D-printing technologies for polymeric formulations are experiencing a huge development due to the complex and specific geometries that can be covered employing additive manufacturing. However, to ensure sustainable growth, it is essential to replace the currently used fossil-based resins with new bio-sourced alternatives. In this study, tunable bis-allylated compounds were efficiently synthesized from cellulose-derived levoglucosenone via a chemo-enzymatic pathway whom greenness has been assessed by E-factor and Eco-Scale. Subsequently, photocuring was employed as an eco-friendly process to polymerize these compounds with a trifunctional thiol using thiol-ene click chemistry. Real-time techniques such as FT-IR, photo-DSC, and photo-rheology were employed to extensively characterize the UV-process. The resulting thermosets were also subjected to a thorough analysis, covering their thermal-mechanical properties and degradation. Owing to the exceptional reactivity of this thiol-ene system, 3-D printed materials were achieved with remarkable precision.
