Synthesis, Characterization and Stabilization Analysis of Ferrofluid Based on Amazon Vegetable Copaifera O. L. Oil
Keywords:magnetite, copaiba oil, magnetic fluid
The Nanoscience and Nanobiotechnology develops several researches using nanostructures with magnetic properties. These nanostructures can have different physical properties depending on their composition and therefore can be used in various applications such as: drug markers and carriers, microelectronics, magnetic separations and environmental applications. Furthermore, the use of natural components in the synthesis of these nanostructures may come to complement these nanomaterials due to their underexplored properties and their renewable origin. This research will aim to carry out a pre-study to analyze the stability of magnetic fluids based on Fe3O4 nanoparticles functionalized with vegetable oil from the Copaifera SPP plant, known as Copaiba. Therefore, the Fe3O4 nanoparticles will be synthesized by the coprecipitation method by hydrolysis in an alkaline solution. Ferrofluid will be prepared by dispersing magnetic nanoparticles, at different concentrations, in the “in natura” oil. For the samples characterization measurements were taken of: UV-vis, FTIR, NIR spectrophotometry, XRD and Magnetic Susceptibility, the temporal analysis was recorded periodically, observing the possible stability of the samples. This work reports that the ferrofluid showed good stability and the magnetic properties associated with the nanoparticles the properties of the Amazon oil used.
