Reproducibility and Compressive Strength Enhancement of Printed Silk Fibroin–Polyethylene Glycidyl Methacrylate Composite Hydrogels Via Cellulose Nanofibers
Silk fibroin (SF) is a natural polymer with excellent biocompatibility and mechanical properties and moderate human body degradability, making SF an interesting candidate for regenerative medicine. Composite materials of SF and polyethylene glycidyl methacrylate (PEGDMA), a biocompatible polymer, attract attention as scaffold materials for regenerative medicine. To the authors’ knowledge, SF–PEGDMA composite hydrogels have thus far not been manufactured using optical fabrication methods, and the change in their compressive properties during their degradation has not been studied. In addition, cellulose nanofiber (CNF), a plant-derived nanomaterial with excellent mechanical properties and biocompatibility, was added to the SF–PEGDMA hydrogels to enhance their mechanical properties. SF–PEGDMA composite hydrogels were three-dimensionally printed using digital light processing. The compressive strength of the obtained hydrogels stored in pure water or phosphate buffer solution temporarily increased and decreased after 4 days. However, after 7 days, the strength decreased to a level similar to that of the specimens which did not contain CNF. In the formability tests, the reproducibility of the model changed with the intensity of the light and the CNF concentration.
期刊介绍:
Strength of Materials focuses on the strength of materials and structural components subjected to different types of force and thermal loadings, the limiting strength criteria of structures, and the theory of strength of structures. Consideration is given to actual operating conditions, problems of crack resistance and theories of failure, the theory of oscillations of real mechanical systems, and calculations of the stress-strain state of structural components.
