Hyperbranched Poly(amidoamine)-modified Multi-walled Carbon Nanotubes via Grafting-from Method

Abstract
Hyperbranched poly(amidoamine) (h-PAMAM)-grafted multi-walled carbon nanotubes (MWNTs) were successfully synthesized by grafting-from method. The modified MWNTs, which gave stable dispersion in organic solvents, were reacted with the fluorescein isothiocyanate (FITC) and then showed strong photoluminescent property.
