Evaluation of Residual Iron of Carbon Nanotubes Treated by Acid

Abstract:

Multiwalled carbon nanotubes treated by hydrochloric acid treatment were in detail analysized by thermogravimetric analysis and SEM. The optimal technological conditions are that the concentration of the solution is 6 mol/L, the treating temperature is 90 °C, the treating time is 4 h and the mass ratio of solution to MWCNTs is 200:1. This result can also be verified by the contrast of SEM photographs of untreated and treated MWCNTs.
