Abstract

Supracolloidal hybrids: Soft polymer-based Janus micelles provide excellent stabilization for multi-walled carbon nanotubes (see scheme) in a variety of solvents, including water. The size ratio of the micelle′s stabilizing corona to adsorbing corona (Janus balance) is decisive for good physisorption and stabilization. The supracolloidal interaction preserves the structural integrity of the nanotubes, which is essential for maintaining their useful properties.
