Claim 2:
3. The aqueous dispersion of claim 1, wherein:
at least one of the multiwall carbon nanotubes has a length equal to or greater than 2 microns, as determined by SEM,
at least one of the multiwall carbon nanotubes has a length to diameter aspect ratio within a range of from 200 to 1000,
there are at least two branches along a 2-micrometer length of at least one of the multiwall carbon nanotube, as determined by SEM,
at least one multiwall carbon nanotube exhibits an asymmetry in a number of walls observed in an area after a branching point relative to an area prior to the branching point, and/or
no catalyst particle is present at or near branching points, as determined by TEM.
