Abstract

A disk-like nanoparticle includes a core layer that comprises a cross-linked multi-vinyl substituted aromatic hydrocarbon and a shell layer that comprises tri-block copolymer chains, each having a first, a second, and a third block. The first and third blocks of the tri-block copolymer chains comprise vinyl aromatic monomer units and are crosslinked with the core. The second block comprises conjugated diene monomer units and comprises a top and bottom axial surface of the disk-like nanoparticle. In the case of a nanoparticle having A-B-C tri-block copolymer chains, the third block comprises a top and bottom axial surface of the disk-like nanoparticle.
