NANOCOMPOSITE AND METHOD OF MAKING THEREOF
(FR)
NANOCOMPOSITE ET SON PROCÉDÉ DE FABRICATION
Abstract:
(EN)
An embodiment of an inorganic nanocomposite includes a nanoparticle phase and a matrix phase. The nanoparticle phase includes nanoparticles that are arranged in a repeating structure. In an embodiment, the nanoparticles have a spherical or pseudo- spherical shape and are incompatible with hydrazine. In another embodiment, the nanoparticles have neither a spherical nor pseudo-spherical shape. The matrix phase lies between the nanoparticles of the nanoparticle phase. An embodiment of a method of making an inorganic nanocomposite of the present invention includes forming a nanoparticle superlattice on a substrate. The nanoparticle superlattice includes nanoparticles. Each nanoparticle has organic ligands attached to a surface of the nanoparticle. The organic ligands separate adjacent nanoparticles within the nanoparticle superlattice. The method also includes forming a solution that includes an inorganic precursor. The nanoparticle superlattice is placed in the solution for a sufficient time for the inorganic precursor to replace the organic ligands.
(FR)
L'invention, selon un mode de réalisation, porte sur un nanocomposite minéral, qui comprend une phase de nanoparticules et une phase de matrice. La phase de nanoparticules comprend des nanoparticules qui sont disposées selon une structure répétée. Dans un mode de réalisation, les nanoparticules ont une forme sphérique ou pseudo-sphérique, et sont incompatibles avec l'hydrazine. Dans un autre mode de réalisation, les nanoparticules n'ont ni une forme sphérique ni une forme pseudo-sphérique. La phase de matrice se trouve entre les nanoparticules de la phase de nanoparticules. Selon un mode de réalisation, la présente invention porte sur un procédé de fabrication d'un nanocomposite de nanoparticules minéral, lequel procédé comprend la formation d'une surstructure de nanoparticules sur un substrat. La surstructure de nanoparticules comprend des nanoparticules. Chaque nanoparticule comprend des ligands organiques fixés à une surface de la nanoparticule. Les ligands organiques séparent des nanoparticules adjacentes à l'intérieur de la surstructure de nanoparticules. Le procédé comprend également la formation d'une solution qui comprend un précurseur minéral. La surstructure de nanoparticules est disposée dans la solution pendant un temps suffisant pour que le précurseur minéral remplace les ligands organiques.
