Carbon nanotube enhanced magnets

Aimants améliorés par des nanotubes de carbone

Abstract

L'invention porte sur l'adjonction d'un matériau carboné, de préférence sous la forme d'un remplissage de nanotubes de carbone et/ou de fibres de nanotubes de carbone, à des substances magnétiques pour en accroître le magnétisme intrinsèque. Le mélange ainsi produit peut si besoin est être fixé par l'adjonction de substances telles que des résines époxydes. Les aimants permanents ainsi obtenus peuvent être utilisés dans des applications dépassant le cadre des aimants permanents non améliorés.
The present invention relates to the addition of carbonaceous material, advantageously in the form of carbon nanotubes, filled or otherwise and/or carbon nanotube fibres to magnetic substances such that the intrinsic magnetism of the magnetic substances is enhanced. The mixture so produced can, if required be fixed through the addition of suitable fixing mediums such as epoxy resin. The resulting fixed, nanotube enhanced, permanent magnets are suitable for use in applications beyond the scope of non-enhanced permanent magnets.
