In a selective solvent, diblock copolymers self-assemble to form spherical micelles consisting of soluble coronas and insoluble cores. This structure has been widely used to increase the stability of many functional materials for various application. Moreover, the precise control of metal, semiconductor, and oxide nanoparticles placement within the micelles were demonstrated. In this study, we present cluster formation of gold nanoparticles (NPs) within PS-PAA micelles. We first incorporated single NPs within polystyrene-block-poly(acrylic acid), PS−PAA micelles, which further develop as building block for the second-level asembling process. The clusters of Au NPs inside PS-PAA micelles were then controlled by variation of temperature, solvent, and salt condition. The emerging cluster-like formation are localized in the center of micellar structure. |
