Patent ID: 8535973

Claim:
A method for producing nanoparticle/block copolymer composites, the method comprising: mixing nanoparticles having an organic ligand L and a block copolymer A-b-B having block repeating units A and B with different solubility parameters in a solvent S to form micelles by self-assembly to produce the nanoparticle/block copolymer composite, wherein the solubility parameters of the organic ligand L, the block repeating units A and B of the block copolymer A-b-B and the solvent S satisfy the following inequalities: 29≦δ S −δ A (1) δ S −δ B ≦29 (2) |δ L −δ A |≦5 or |δ L −δ B |≦5 (3) 29≦δ S −δ L (6) wherein δ S , δ A , δ B and δ L represent the solubility parameters of the solvent S, the block repeating unit A, the block repeating unit B and the ligand L, respectively, wherein the organic ligand is present on the surface of the nanoparticle in the micelle, wherein the nanoparticles have a diameter of about 1 nanometer to about 100 nanometers, and wherein the micelle comprises the nanoparticle, the organic ligand disposed on the surface of the nanoparticle, and the block copolymer.
