Abstract
A method for producing nanoparticle/block copolymer composites is provided. The method includes 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. 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−δ  (1)δ−δ≦29  (2)|δ−δ|≦5 or |δ−δ|≦5  (3)in which δ, δ, δand δrepresent the solubility parameters of the solvent S, the block repeating unit A, the block repeating unit B and the ligand L, respectively. According to the method, the inherent electrical, magnetic, optical, chemical and mechanical properties of the nanoparticles can be maintained or improved without the need to modify the surface of the nanoparticles.
