Relationship between oxidation treatment method and carboxylic group content on the surface of MWCNTs
Source abstract
Abstract
Carboxylic groups were produced on the surface of MWCNTs by oxidation treatment.Carboxylic group contents were quantitively analyzed by FTIR,TGA and XPS.Results show that TGA and XPS analysis give similar carboxylic group contents on the surface of MWCNTs.For 2.5mol/L nitric acid oxidation for 4 h,mixed acid oxidation for 4 h,and mixed acid oxidation for(4 h) and then 20 % H_2O_2 oxidation for 2 h,4.80,(5.35) and 7.55 mol% of carboxylic groups on the were respectively produced.
