Surface Modification of Multiwall Carbon nanotubes (MWCNTs) was performed by a mixture of sulfuric acid and nitric acid . Pristine MWCNTs, vacuum heating dry MWCNTs, and vacuum freezing dry MWCNTs were prepared. According to the results, acid treatments give more carboxyl groups on the Surface of the MWCNTs. In addition, vacuum freezing dry treatment provides less damaged MWCNTs than vacuum heating dry treatment.
