Abstract

Namen diplomskega dela je bil ugotoviti, s katerim načinom sinteze lahko sintetiziramo magnetne nanodelce CuNi z ustrezno sestavo za nadaljnjo uporabo pri pripravi magnetnih tekočin, ki bi bile primerne za uporabo pri magnetni hipertermiji. S pomočjo rentgenske praškovne difrakcije (RPD) smo karakterizirali velikost nastalih nanodelcev zlitine in določili faze v vzorcih. Fizikalne lastnosti vzorcev (izgubo mase) smo, pri kontroliranem segrevanju, določili s termogravimetrično analizo (TGA). Magnetne lastnosti nastalih nanodelcev smo izmerili z suscepto-magnetometrom DSM — 10. Na koncu smo preučili še morfologijo delcev s transmisijskim elektronskim mikroskopom (TEM). Rezultati so pokazali, da je najprimernejša metoda za sintezo magnetnih nanodelcev CuNi z različnimi sestavami mehanokemijska metoda. Sintetizirani delci so kazali močne magnetne lastnosti. Čas mletja vpliva na velikost nastalih nanodelcev in stopnjo zreagiranosti reaktantov.

Secondary title: Synthesis of Cu-Ni nanoparticles of varying compositions
Secondary abstract: The aim of this work was to determine, which way of synthesis is the most succesful for preparation of magnetic nanoparticles CuNi with suitable composition for further preparation of magnetic fluids, which can be used in magnetic hyperthermia. The size of magnetic nanoparticles was estimated with Scherrer equation. Samples were characterized with XRD analysis. Physical properties (loss of weight) of the samples were, during controlled heating, measured with termogravimetric analysis (TGA). Magnetic properties of the samples were measured with DSM – 10 magnetometer. At the end we studied morphology of the synthesized nanoparticles with transmission electronic microscope (TEM). The results showed that the most suitable method of synthesis of magnetic nanoparticles CuNi with varying composition is mechanochemical method. Synthesized nanoparticles were strongly magnetic. Time of milling has effect on size of synthesized nanoparticles.
