Effect of Acid Oxidation on the Dispersion Property of Multiwalled Carbon Nanotubes

摘要: A means of dispersion multiwalled carbon nanotube (MWCNT) via mixed acid (HNO3 and H2SO4) oxidation with different treatment durations was investigated through the solubility study treated nanotubes in some common solvents. Fourier transformed infrared (FTIR) characterization reaction products revealed that surface MWCNTs successfully functionalized acidic groups. The acid‐base titration demonstrated amount groups increased parallel refluxing duration. modified were found to be well dispersed polar solvents, such as ethanol water due presence hydrophilic functional on raw MWCNTs. Such chemical modification properties will pave way towards realistic applications nanotechnology world.
