METHOD FOR OBTAINING MATERIALS WITH SUPERPARAMAGNETIC BEHAVIOUR
The invention relates to a method for obtaining materials, comprising the treatment of solids by means of interaction with ferrofluids in order to provide the end product with superparamagnetic properties at moderate temperatures. These superparamagnetic materials are produced by assembling nanopart...

| description | The invention relates to a method for obtaining materials, comprising the treatment of solids by means of interaction with ferrofluids in order to provide the end product with superparamagnetic properties at moderate temperatures. These superparamagnetic materials are produced by assembling nanoparticles of metal oxides, which are associated with a compound having a surfactant effect, such as oleic acid, and which are carried by a non-aqueous ferrofluid, with a different type of solid material, preferably having adsorbent properties, absorbent properties or reagent- and product-supporting properties. The invention also relates to the resulting material, as well as to the use thereof in different applications, such as for use: as adsorbents, as sensors, as ion exchangers, in the elimination of toxic or radioactive contaminants, in chromatographic separation processes, in medical and biological applications, as supports for biological materials such as enzymes, as polymer fillers, in the absorption of electromagnetic radiation, and as catalyst and metal oxide precursors. |
