Synthesis and Performance of Dopa-modified Multiwalled Carbon Nanotubes

摘要：

　　The Dopamine-modified multiwalled carbon nanotubes (MWNT-Dopa) were synthesized by chemical reaction between dopamine (Dopa) and multiwalled carbon nanotubes which oxidazed by mixed-acid (MWNT-COOH).The structure of MWNT-Dopa were analyzed by Fourier transform infrared spectroscopy (FT-IR),Thermogravimetric (TG),Transmission electron microscopy (TEM),and X-ray photoelectron spectroscopy (XPS) techniques and the dispersity of MWNT-Dopa were studied by Dispersion stability analyzer.The results show that dopamine has been grafted on multiwalled carbon nanotubes successfully,and a dopamine layer which wraps on the surface of multiwalled nanotubes make multiwalled nanotubes have outstanding dispersity in water.
