multi-walled carbon nanotube functionalization by Oxone
What is it about?
In this work, multi-wall carbon nanotube (MWCNT) was successfully modiﬁed using aqueous solution of Oxone as a new oxidant. The effect of oxidation temperature on various characteristics of the treated MWCNTs was also investigated. FTIR and titration analysis proved the formation of carboxyl, carbonyl and epoxide groups at the surface of MWCNTs. The concentration of the functional groups increased as the modiﬁcation temperature increased. The presence of such oxygen containing groups at the surface of MWCNTs justiﬁed the long time stability of the treated MWCNTs suspensions in water and methanol. The modiﬁed MWCNTs showed higher entanglement compared to row MWCNT due to the cross-links adjacent effect of pendant functional groups. Finally, it was concluded that Oxone oxidation process destroys the structure of the MWCNTs, but not severe enough to unzip the MWCNTs.
Why is it important?
In this study the functionalization of MWCNT with Oxone as a new and effective oxidant was studied. The effect of oxidation temperature on various characteristics of the treated MWCNTs was also investigated.
