Dispersions comprising high surface area nanotubes and discrete carbon nanotubes

A dispersion comprising:

• oxidized, discrete carbon nanotubes wherein the discrete carbon nanotubes comprise an interior and exterior surface, each surface comprising an interior surface oxidized species content and an exterior surface oxidized species content, wherein the interior surface oxidized species content is in the range of from about 0.01 to about 3 weight percent relative to carbon nanotube weight, wherein the exterior surface oxidized content is from about 0.1 to about 65 weight percent relative to carbon nanotube weight and wherein the interior surface oxidized species content differs from the exterior surface oxidized species content by at least 20% in magnitude;
• and
• high-surface area carbon nanotubes, wherein the high-surface area nanotubes are single-wall nanotubes, wherein the BET surface area of the high-surface area nanotubes is from about 550 m2/g to about 1500 m2/g according to ASTM D6556-16 and wherein the aspect ratio is at least about 500 up to about 6000;
• wherein the sum of the weight of the oxidized, discrete carbon nanotubes and the high surface area carbon nanotubes is in the range of from about 0.1 to about 30% by weight based on the total weight of the dispersion.
