Abstract

Magnetite/hydroxyapatite/chitosan rods have been prepared via in situ compositing method. The mechanical properties were characterized and evaluated for suitability as a bone repair materials. Scanning electron microscopy (SEM) was carried out to investigate the microstructure of CS/HA/Fe₃O ₄ composite. Effect of inorganic content on the mechanical properties of the CS/HA/Fe₃O₄ composite was also investigated. It was observed that the mechanical properties of the composite in the dry condition improved as the percentage of CS content increased. Mechanical properties of CS/HA/Fe₃O₄ composite rod are much better than that prepared via traditional method. Bending strength, bending modulus of CS/HA/Fe₃O₄ composite are 118.5 MPa, 2.3 GPa, respectively. All of these material properties are twice or three times stronger compared with that of nature bone of human being.
