Multiple-walled carbon nanotubes (MWNTs) were chemically modified by a ligand-exchange
reaction of ferrocene (Cp-Fe-Cp). The modified MWNTs (Cp-Fe-MWNTs) were next monolithiated by tert-butyllithium and terminated by p-chloromethylstyrene (pMS). The pMS-terminated species (pMS-Cp-Fe-MWNTs) were then functionalized with living polystyryllithium anions via anionic polymerization.
The resulting polystyrene-functionalized MWNTs exhibited as polymeric nanocomposites and were soluble
in common organic solvents showing distinct colors from a neat polystyrene solution. Syntheses results
and the characterization data of the functionalized MWNTs, collected from GC-MS, NMR, electron
microscopy, and optical spectroscopy, are presented and discussed.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
