Abstract
A multi-layer nano-particle composition including a polymer core and at least two additional layers is provided. The nano-particles have a mean average diameter less than about 100 nm. The nano-particles can be modified via, for example, hydrogenation or functionalization. The nano-particles can be advantageously incorporated into rubbers, elastomers, and thermoplastics.
