Structural changes in multi-walled carbon nanotubes (CNTs) resulting from covalent functionalization during oxidation were studied by transmission electron microscopy, X-ray photoelectron spectroscopy (XPS) and Raman spectroscopy. Strong correlation is found between the oxidation progress (i.e. incr...
