They often have interesting properties, such as poor heat conductivity (which makes them good insulators) and low friction (which makes them slippery).

Because the two materials exhibit a high thermal conductivity, they allow the device to cool more efficiently while distributing said heat -- 25 percent quicker than the pure copper in many pieces of tech.

That does not affect their electrical conductivity, but nanoscale particles like this are known to scatter and obstruct the passage of heat through imperfectly understood quantum-mechanical processes.
