Abstract

A novel noncovalent approach was developed for the functionalization of multiwalled carbon nanotubes (MWNTs) using an amphiphilic copolymer of PVP-co-PAH containing pyrene pendants. A homogeneous polymer layer was formed on the surface of MWNTs, and the wrapped copolymer layer with a thickness of about 17.7 nm was found. The noncovalent modified MWNTs were dispersed very well in solvent of dimethylformamide (DMF), water and chloroform (CHCl₃), and the high stability of dispersed suspensions could be maintained for more than 2 months without observed MWNT precipitation. In addition, the dispersing behavior of the noncovalent functionalized MWNTs by PVP-co-PAH in a solvent mixture of water/CHCl₃ was also investigated, and it was found that a carbon nanotube layer was formed at the water/CHCl₃ interface.
