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 1 H NMR, Fourier transform infrared (FTIR), ultraviolet-visible (UV-vis), Raman spectrometry and transmission electron microscopy (TEM).
