Sekundarni naslov: | Magnetic properties of magnetic nanoparticles (MNPs) with different polymer coatings |
Sekundarni povzetek: | Nanoparticles have an increasing potential in various industries due to their exceptional physical and chemical properties. Tailoring the magnetic properties of nanoparticles is THE key to designing new multifunctional materials. In this master's thesis, we studied the influence of different ratios of Fe2+ and Fe3+ ions on the structural and magnetic properties of nanoparticles. MNPs were synthesized by the co-precipitation method. The influence of different polymer coatings (aminosilane or arabinogalactan) on the properties of modified MNPs was investigated as well. Such polymer coating prevents agglomeration of MNPs and increases stabilization of the particles. MNPs coated with polymer coatings are usually more biocompatible. The synthesized particles were characterized by analytical methods such as FTIR, TGA and VSM. The analysis confirmed the presence of polymer coatings on the surface of MNPs. The thermal stabilities of modified MNPs were determined. In addition, all modified MNPs exhibited superparamagnetic nature. MNPs with an arabinogalactan coating in the ratio Fe²⁺: Fe³⁺ = 2:1 even demonstrated antibacterial efficiency against E. coli and S. aureus. |
