Title (EN) MAGNETIC NANOPARTICLES AND MAGNETORHEOLOGICAL FLUID COMPRISING SAME
(FR) NANOPARTICULES MAGNÉTIQUES ET FLUIDE MAGNÉTORHÉOLOGIQUE COMPRENANT CELLES-CI
Abstract:
(EN) A nanoparticle composition comprises a ferromagnetic or superparamagnetic metal nanoparticle, and a functionalized carbonaceous coating on a surface of the ferromagnetic or superparamagnetic metal nanoparticle. A magnetorheological fluid comprises the nanoparticle composition.
(FR) Composition de nanoparticules qui comprend une nanoparticule métallique ferromagnétique ou superparamagnétique, et un revêtement carboné fonctionnalisé situé sur une surface de ladite nanoparticule métallique ferromagnétique ou superparamagnétique. Un fluide magnétorhéologique selon l’invention comprend la composition de nanoparticules.
