Frictional Properties of Carbon Nanotube Films with a Load Range from Micronewton to Millinewton Using mm Size Balls

Tribological properties of a vertically aligned carbon nanotube (CNT) film with a thickness of approximately 700 μm under millinewton and micronewton level loads were investigated using a 1 mm radius ball. At the beginning of frictional slidings, friction forces were high, and then decreased...
