Abstract
A method encapsulates nanoscale material by producing a suspension of the nanostructure material in a first solvent using a micelle surrounding the nanostructure material. The micelle surrounding the suspended nanostructure material is swollen by adding to and mixing with the suspension an immiscible phase second solvent containing a precursor. The precursor is then reduced by adding a reducing reactant selectively soluble in the first solvent that reacts to the precursor containing reactant selectively solvated in the second solvent to encapsulate the nanostructure material. A metal-nanostructure composite can be provided by collecting and mixing the metal-shell encapsulated nanostructure product produced by the aforementioned method into a metal matrix.
