Abstract

Cette invention concerne un procédé qui permet de moduler la forme de particules de synthèse, et de produire des matériaux et des dispositifs contenant des nanostructures orientées et étendues. Ce procédé consiste à effectuer des processus de mise en forme et de croissance de particules sous l'action de champs électriques et magnétiques externes. Ce procédé permet de produire des particules discrètes, contenant des métaux et magnétiques, y compris des particules métalliques amorphes, dont la forme se modifie de manière prédéterminée. Les particules passent ainsi d'une forme de sphère ou de disque à une forme anisotropique, ellipsoïdale et aciculaire, les dimensions caractéristiques allant de un à plusieurs centaines de nanomètres. Ce procédé permet également de produire des grappes de particules en chaîne. Il est également possible de produire des nanostructures orientées, métalliques et en forme de fils (nanotubes) dont le diamètre transversal est approximativement de 10 nm ou moins, ainsi que des systèmes monocouche ou multicouches sur un substrat solide. Ce procédé peut être utilisé dans la production de matériaux métallo-polymères, y compris des matériaux de type film fin, que l'on utilise dans la fabrication d'éléments fonctionnels en électronique, en nanotechnologie, en électrotechnique ainsi que dans des systèmes et des dispositifs d'optique et d'optique non linéaire. Ce procédé peut également être utilisé dans la production de nouveaux éléments de mémoire magnétique et de supports d'informations magnétiques, ainsi que dans la production de particules colloïdales qui sont utilisées dans des fluides magnétiques et magnéto-rhéologiques et dans la production de revêtements absorbants et protecteurs.
