Study on attachment of highly branched molecules onto multiwalled carbon nanotubes

The modification chemistry of the open ends, the exterior walls, or the interior cavity of the carbon nanotubes (CNTs) is expected to play a vital role in tailoring the properties of these materials. In this paper, we describe a method of surface modification of multiwalled carbon nanoparticles (MWNTs) using highly branched molecules covalently attached onto the surface of MWNTs. Resultant products were characterized using H-1 NMR, Fourier transform infrared (FTIR), ultraviolet-visible (UV-vis), Raman spectrometry and transmission electron microscopy (TEM).
