Journal of Polymer Science, Part A: Polymer Chemistry, 2013, 51 (3) , 614-623.

The aggregation of a series of linear oligo(ethylene glycol) methacrylate (co)polymers with low molar mass dispersities and well-defined structure was followed in aqueous solutions using light scattering and turbidimetry. The influence of the molar mass, copolymer composition, length of the oligo(ethylene glycol) side chain, concentration of aqueous solution, and heating rate onto the mesoglobule sizes was investigated.

Janus Micelles as Effective Supracolloidal Dispersants for Carbon Nanotubes

Gröschel, A., Löbling, T., Petrov, P., Müllner, M., Kuttner, C., Wieberger, F., Müller, A.H.E.
Angewandte Chemie International Edition

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.
