Functionalization of carbon nanohorns with polyethylene oxide: synthesis and incorporation in a polymer matrix.
In the present work we describe, for the first time, the chemical functionalization of oxidized CNHs with a polymer, namely polyethylene oxide, in order to make them soluble in a variety of solvents. The success of the covalent functionalization of CNHs has been confirmed by a variety of complementary techniques, including thermogravimetric analysis, infrared and UV-vis spectroscopy. The solution behavior of the polymer functionalized CNHs has been studied in aqueous solutions at different temperatures by means of light scattering. Finally, the incorporation of the functionalized carbon nanostructure in poly(hydroxyl styrene) (PHOS) matrix is discussed.
