Polylactic acid (PLA)-based composite has been widely used in tissue engineering. To modify the material's properties, inorganic substances have been used to form nanoparticle-PLA composites. The aim of this study is to develop a novel magnetic biodegradable composite. Nanoscale magnetite (Fe 3O4) was incorporated into a poly-L-lactide (PLLA) matrix with proportions of 0%, 5%, 10%, and 15% (w/w). Injection molding was carried out to produce the nano-magnetite-PLLA composite samples. X-ray diffraction (XRD), differential scanning calorimetry (DSC), superconducting quantum device (SQUID), and three-point bending were performed to test the physical properties of the magnetite-PLLA composite. The results showed that the magnetite-PLLA composite exhibited typical ferromagnetic hysteresis loops. The addition of nanoscale magnetite significantly increased the magnetic flux density of the PLLA composite. These results suggest that the magnetite-PLLA composite has the potential to be used for future applications in tissue engineering.
