| Abstract | ||
| The colloidal non-aqueous precipitation method was used to prepare a biocompatible magnetic ceramic–polymer composite [Hydroxyapatite/ Polyvinylachohol (HAP/PVA)] for medical applications. The starting materials used for preparing hydroxyapatite (HAP) were calcium nitrate and diammonium hydrogen phosphate, while the biodegradable polyvinylachohol (PVA) and nanosized iron oxide particles (γ-Fe2O3) were used to generate a biocompatible magnetic gel film. The results showed that the specimens of composite containing up to 30wt% hydroxyapatite didn’t explore any of phase separation; further the incorporated of the ferrite enhanced the affectivity and the stability of the composite. The surface morphology and magnetic properties of the gel films were studied and the magnetization measurements were carried out at 5-300Kº. it showed that no remnant magnetization at 300 Kº, but at 5 Kº hysteretic loop was observed leading to confirm that the superparamagnetic nature of the nanosized maghemite particles didn’t affect in presence of the polymer and its behavior considered as superparamagnetic material. | ||
