Figure 1: Physical Characterization of dMWCNTs.

Figure 1:

A) Representative SEM micrographs of entangled CNTs aggregated tubes and individualized dMWCNTs and PEG-dMWCNTs are discrete and substantially free of contaminants (silicon wafer seen in backdrop). B) TEM analysis proves they have an outer diameter of 10.74 nm +/− 2.46 (SD) nm and an inner diameter of 4.959 nm +/−1.07 (SD). C) Molecular spectral properties using FTIR of dMWCNTs and functionalized PEG-dMWCNTs. D) TGA comparison between CNTs and dMWCNTs show an increase in oxidative functionalization and removal of metal catalyst during the cleaning process to yield dMWCNTs from CNTs E) TGA comparison between dMWCNTs and PEG-dMWCNTs show an increase in functionalization due to the presence of PEG covalently attached to the surface.
