COOH Functionalized Carbon
Nanotubes (Research Grade, high purity) |
We start with
our purified PD15L5-20 multiwall carbon nanotubes (purity >95% by TGA) and perform a
reflux in sulfuric/nitric acid to functionalize the surfaces of these nanotubes.
This process results in a large concentration of carboxyl (-COOH) groups on the
nanotube surface, and may also generate other groups (e.g. –OH) as well. After
functionalization, these carboxylated nanotubes have 2-7 wt% COOH by
titration. Images below are FTIR spectrum and Raman Spectrum Data of our COOH functionalized nanotubes. Click on the images to view in PDF.
