Abstract
The disclosure includes a lubricant composition further including: (a) at least one synthetic base oil and optionally at least one additive and (b) carbon nanotubes, the composition having a weight percentage of carbon nanotubes (b) relative to the total amount of base oils (a) of the composition of between 0.15 and 3.50%, the ratio between the weight percentage of carbon nanotubes, and the apparent density of the powder of carbon nanotubes, expressed in g/1 and measured according to the standard ISO 60-ASTM D1895 being greater than 102.
