Abstract:
1. A method for making disk-like nanoparticles in a liquid hydrocarbon medium, the nanoparticles having a core layer and a shell layer, the shell layer comprising tri-block copolymer chains having a first block, a second block, and a third block, the method comprising the steps of: polymerizing a conjugated diene monomer with a multi-functional initiator; copolymerizing a vinyl aromatic monomer to form the first and third blocks, thereby producing the tri-block copolymer chains; assembling the tri-block copolymer chains in the liquid hydrocarbon medium to form micelle structures; and crosslinking a multiple-vinyl-substituted aromatic hydrocarbon with the tri-block copolymer chains in the micelle structures to form a cross-linked core and to form polymer nanoparticles.
