Chemical synthesis of Al2O3–Fe2O3 powders added to a PCL matrix

In recent years, magnetic particles have attracted attention in the scientific field for their potential applications in biomedical topics. Fe 2 O 3 –Al 2 O 3 magnetic particles were obtained by sol–gel synthesis at three-atmosphere conditions. The powders were characterized by DSC/TGA, XRD, and SEM...

Description
Summary:In recent years, magnetic particles have attracted attention in the scientific field for their potential applications in biomedical topics. Fe 2 O 3 –Al 2 O 3 magnetic particles were obtained by sol–gel synthesis at three-atmosphere conditions. The powders were characterized by DSC/TGA, XRD, and SEM. A vibrating sample magnetometer (VSM) evaluated the magnetic behavior of the composite material. 1.5 wt% of the nanoparticles were added to a polycaprolactone matrix to obtain a homogeneous polymeric-magnetic composite thin film with an average thickness of 1.43 μm. The results showed the obtainment of Fe 2 O 3 –Al 2 O 3 systems which can be used as magnetic wires for remotion of biomarkers. Graphic Abstract Morphology-sintered S2 sample and TGA/DSC measurements of the obtained powders by sol–gel synthesis.
