A simple way to chemically react single-wall carbon nanotubes with organic materials using ultrasonication

Ultrasonication of single-wall carbon nanotubes (SWNTs) in a monochlorobenzene (MCB) solution of poly(methyl methacrylate) (PMMA) enabled us to react SWNTs with MCB or PMMA chemically. After the SWNTs reacted with these organic materials, they turned into ragged SWNTs (r-SWNTs) with many defects in the sidewall when burned in oxygen. We think that the sonochemical reaction of SWNTs and organic materials is a simple method to functionalize SWNTs.
