【 摘 要 】

Biopolyesters such as synthetic poly(propylene fumarate) (PPF) are widely used in the biomedical field. In order to be used as orthopaedic scaffolds, their stiffness and strength have to be improved. Inorganic boron nitride nanotube (BNNT) 1D nanomaterials have recently attracted a lot of interest as reinforcing fillers of polymers due to their outstanding physical properties. This article deals with the preparation and mechanical characterization of PPF/BNNT composites with nanotube concentrations in the range of 0.1-5 wt%. Results demonstrate that the composites exhibit rigidity enough to be used for tissue engineering applications.
