Warner, John J. published the artcile3D printable non-isocyanate polyurethanes with tunable material properties, Product Details of C17H28O8S4, the main research area is printable nonisocyanate polyurethane tunable material property.
Green chem.-based non-isocyanate polyurethanes (NIPU) are synthesized and 3D-printed via rapid, projection photopolymerization into compliant mechanisms of 3D structure with spatially-localized material properties. Trimethylolpropane allyl ether-cyclic carbonate is used to couple the unique properties of two types of reaction chem.: (1) primary diamine-cyclic carbonate ring-opening conjugation for supplanting conventional isocyanate-polyol reactions in creating urethane groups, with the addnl. advantage of enabling modular segment interchangeability within the diurethane prepolymers; and (2) thiol-ene (click) conjugation for non-telechelic, low monodispersity, quasi-crystalline-capable, and alternating step-growth co-photopolymerization The extent of how these processes utilize mol. tunability to affect material properties were investigated through measurement-based comparison of the various polymer compositions: frequency-related dynamic mech. anal., tension-related elastic-deformation mech. anal., and material swelling anal. Stained murine myoblasts cultured on NIPU slabs were evaluated via fluorescent microscopy for “”green-chem.”” affects on cytocompatibility and cell adhesion to assess potential biofouling resistance. 3D multi-material structures with micro-features were printed, thus demonstrating the capability to spatially pattern different NIPU materials in a controlled manner and build compliant mechanisms.
