Resumen o descripción
Recently, an oil-in-water microemulsion reaction method was developed for the
preparation of nanomaterials. This novel method allowed a better control of the
size and crystallinity of the obtained nanoparticles compared to other methods.
The system used in this study was water, n- alkyl fatty alcohol ethoxylated
surfactants and hexane. A selected microemulsion composition was used for
the synthesis of 5-10 nm Mn-Zn ferrite nanoparticles which were characterized
by High Resolution Transmission Electron Microscopy (HRTEM) and X-Ray
Diffraction. In addition, magnetic properties of the Mn-Zn ferrite nanoparticles
were assessed. Hence, magnetic nanostructured materials were synthesized in
a predominantly aqueous environmentally friendly media (oil-in-water
microemulsion). The properties of Mn-Zn ferrite nanoparticles were compared to
those prepared using the water-in-oil microemulsion reaction method.
