In Situ Polymerization Initiated by Single-Walled Carbon\nNanotube Salts

Abstract

Nanotube salts serve as initiators for the in situ polymerization of methyl methacrylate onto the surface\nof the nanotubes. The poly(methyl methacrylate)-grafted single-walled carbon nanotubes (SWNTs) are\nsoluble in chloroform, tetrahydrofuran, and acetone. Atomic force microscopy images and Raman\nspectroscopy show that the SWNT bundles were exfoliated during the reduction, leading mostly to\nindividual tubes.
