Abstract

An innovative and effective approach is introduced to functionalize multi-walled carbon nanotubes (f-MWCNTs) by in-situ chemical precipitation of hydroxyapatite (HA) to improve their magnetic properties. The HA/f-MWCNTs nanocomposites are obtained by pressureless sintering in vacuum atmosphere. The carboxyl functional group (-COOH) is introduced by an acid treatment on the MWCNT surface. Magnetic hysteresis measurement reveals that HA/f-MWCNTs nanocomposites exhibit excellent hard ferromagnetic properties with saturation magnetization (M_S) of 0.233 emu/g and coercivity (H_C) of 2985.53 Oe at room temperature. The maximum magnetic hysteresis loss of 0.44 kJ/m³ induces an expected heat generation and it is expected that this nanocomposite has potential to be used as a biomaterial for hyperthermia treatment of bone cancer and other biomedical applications.
