Mechanical Properties Tailoring of 3D Printed Photoresponsive Nanocellulose Composites

Advanced Functional Materials 2020 Volume 30, Issue 35, Article 2002914

3D printing technologies allow control over the alignment of building blocks in synthetic materials, but compositional changes often require complex multimaterial printing steps. Here, 3D printable materials showing locally tunable mechanical properties are produced in a single printing step of Direct Ink Writing. These new inks consist of a polymer matrix bearing biocompatible photoreactive cinnamate derivatives and up to 30 wt% of anisotropic cellulose nanocrystals. The printed materials are mechanically versatile and can undergo further crosslinking upon illumination. When illuminating the material and controlling the irradiation doses, the Young’s moduli can be adjusted between 15 and 75 MPa. Moreover, spatially…
