Polymer compositions including functionalized carbon nanotubes and exhibiting reduced sloughing

A polymer composition comprising:

• functionalized carbon nanotubes, the functionalized carbon nanotubes having multiple walls and one or more oxygen based functional groups;
• and
• one or more polymers,
• wherein a molded part formed from the polymer composition has improved sloughing properties as measured by liquid particle analysis (LPC) and as compared to another molded part formed from another composition comprising non-functionalized carbon nanotubes,
• wherein the other composition comprises the one or more polymers in substantially similar weight percentages as the one or more polymers of the polymer composition and comprises the non-functionalized carbon nanotubes in a substantially similar weight percentage as the functionalized carbon nanotubes of the polymer composition, and
• wherein the functionalized carbon nanotubes have an oxidation level between 3 and 25 wt % as determined by thermogravimetric analysis (TGA).
