Abstract
Size-confined nanocomposite powders and methods for their manufacture are provided by coating fine powders with a nanoscale powder of a different composition. The nanocomposite plastics disclosed offer performance characteristics approaching those of metals and alloys. The nanocomposite powders are alternatively used for dispersion strengthening of metals, alloys, and ceramics. Novel materials based nanotechnology for energy devices and programmable drug delivery are disclosed.
Claims20
A method of forming interface engineered material comprising:
- selecting a fine powder of a material of first composition;
- selecting nanoparticles of a second composition different an the first composition;
- chemically bonding the nanoparticles to the surface of the fine a powders thereby creating a nanocomposite powder with an interfacial layer on the fine powder surface. said interfacial layer of third composition distinct from the first composition and the second composition, and wherein the composition of said interfacial layer results from the chemical bonding of said nanoparticles of the second composition and the fine powders of the first composition.
A nanocomposite powder comprising fine powders of first composition and nanoparticles of second composition, wherein the nanoparticles are chemically bonded to the fine powders there creating a nanocomposite powder with an interfacial layer on the fine powder surface, said interfacial layer of composition distinct from the first composition and the second composition, and wherein the composition of said interfacial layer results from the chemical bonding of said nanoparticles of the second composition and the fine powders of the first composition;
- and
- wherein the size-confined nanocomposite powder has an average domain size of less than 5 micron.
