Novel carbon nanotube microcapsules were prepared by oil in water (O/W) Pickering emulsions without any surfactant used. The oxygen plasma treatment introduced several hydrophilic groups on carbon nanotubes resulting in the improved aqueous dispersion. The plasma-treated carbon nanotubes were self assembled at the interface between water and oil phases. Contact angle measurement and XPS analysis proved the hydrophilic formed on carbon nanotubes. The content of carbon nanotubes played an important role in determining both the morphology and size of microcapsules. (C) 2010 Elsevier B.V. All rights reserved.
