A method is provided for the preparation of nanomaterials, which involves the dissolution and/or suspension of a combination of (a) one or more resin substrate materials and (b) one or more magnetic nanoparticutate substances, in a medium made from one or more ionic liquids, to provide a mixture, and recovering the solid nanomaterial by combining the mixture with a non-solvent (solvent for the ionic liquids but not the other components), while also applying an electromagnetic field to the mixture during the recovering step to align the magnetic nanoparticulate substances, along with the use of the resulting nanomaterials to provide unique information storage media, particularly in the form of sheets or films.
L'invention concerne un procédé de préparation de nanomatériaux, qui consiste à dissoudre et/ou mettre en suspension une combinaison de: (a) un ou plusieurs matériaux substrat de résine, et (b) une ou plusieurs substances nanoparticulaires magnétiques, dans un milieu constitué d'un ou de plusieurs liquides ioniques, pour obtenir un mélange, et récupérer le nanomatériau solide en associant le mélange à un non solvant (solvant pour les liquides ioniques mais pas les autres composants), tout en appliquant un champ électromagnétique au mélange au cours de la récupération pour aligner les substances nanoparticulaires magnétiques, et utiliser enfin les nanomatériaux pour former un milieu de stockage d'information unique, particulièrement sous forme de feuilles ou de films.
