Unique Phase‐Separation Structures of Block‐Copolymer Nanoparticles

Abstract

Block-copolymer nanoparticles with lamellar phase-separation structures (see Figure) have been prepared by a slow-precipitation process. Regular-sized polymer nanoparticles are formed after evaporation of a good solvent from a polymer solution containing a non-volatile poor solvent and a volatile good solvent.
