Study of The Mechanical Property of Magnetite/ Hydroxyapatite/ Chitosan Nano-Composite


Article Preview

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/Fe3O4 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.
