OA Coated Fe3O4 Nanoparticles

Product Name

Name:a>OA Coated Fe3O4 Nanoparticles

^{Product Overview}

High temperature pyrolysis method was used to prepare oleic acid modified iron oxide nanoparticles, and oleic acid was added as a surfactant to a solution containing iron precursor. Oleic acid not only helps to control the growth of nanoparticles, but also forms a stable coating on the surface of the particles.

Heat the solution containing iron precursor and oleic acid to a high temperature, usually around 300 ° C, to promote the thermal decomposition of the iron precursor. At high temperatures, iron precursors decompose to produce iron atoms, which aggregate to form magnetic nanoparticles.

During the pyrolysis process, iron nanoparticles react with oxygen in the air to form Fe3O4.
