Zusammenfassung: | The invention relates to a process for preparing magnetic nanostructures to be employed in security paper manufacturing. According to the invention, the process consists in magnetite synthesis using the method of in-situ co-precipitation, followed by the adsorption of β-glycerol phosphate, 2-phospho-L-ascorbic acid or D-glucose-6-phosphate on the surface of magnetite nanoparticles, after which the kaolinite adsorption is performed with formation of kaolinite-based magnetic nanoparticles, having a value of saturation magnetization of 25 emu/g. |
