Synthesis and structure-property correlations of polyurethanes for additive manufactured biomedical materials

In recent years, 3D printing has gained significant traction in tissue engineering for scaffold creation, owing to its precision, manufacturing convenience, and rapid production capabilities. Stereolithography (SLA) and direct ink writing (DIW) stand out as the predominant techniques in this domain. Nonetheless, the availability of biodegradable and biocompatible polymers, notably within the polyurethane (PU) group, for 3D printing remains limited.
This study aimed to develop biodegradable, biocompatible, and printable PUs, encompassing isocyanate-based and non-isocyanate-based polyurethanes, and their composites, specifically tailored for nerve and skin regeneration. Photo-cross-linkable PU resins and a conductive composite derived from the resin were successfully synthesized and printed with precise geometries. Moreover, a novel series of non-isocyanate-based polyurethanes (NIPUs) utilizing various diamines was synthesized successfully, with an investigation into the correlation between polymer structure and resulting properties. Subsequently, a biocompatible, antibacterial hydrogel composite was synthesized using a particular variant of NIPUs.
