Colloidal nanoparticles have been shown to assemble into a variety of superstructures such as worms, ribbons, and chains. Directional attraction between colloidal nanoparticles with orthogonal repulsion to the attraction can produce linear supracolloidal chains. In this presentation, we demonstrated supracolloidal chains of diblock copolymer micelles. In a solvent preferable to the polar core block, spherical micelles with the cross-linked cores were converted to micelles with the corona reorganized into two non-polar patches and the core exposed to the solvent. Subsequently, the increase of the polarity of the solvent resulted in the formation of supracolloidal chains by linear assembly of these colloidal micelles. With two copolymers having different molecular weight, we were also able to synthesize supracollodial random and block chains. Furthermore, we functionalized the linear superstructures by encapsulating nanoparticles or fluorophores into the core of the micelles. |
