Abstract
Multiwalled carbon nanotubes (MWCNTs)/fullerenol composites were prepared through a facile method. Poly (acryloyl chloride) (PACl) was first grafted onto oxidized MWCNTs through the reaction between the acyl chloride groups of PACl with the hydroxyl groups on the surface of MWCNTs. The PACl with multiple acyl chloride groups provided more active points for further reactions. Subsequently, the remaining acyl chloride groups of PACl were allowed to react with the hydroxyl groups of fullerenols leading to the covalent attachment of the latter onto the grafted PACl chain. The MWCNTs/fullerenol composites thus obtained were characterized using Fourier transform infrared spectrometer (FTIR), transmission electron microscopy (TEM), and thermal gravimetric analysis (TGA).
