Rougher is more slippery: How adhesive friction decreases with increasing surface roughness due to the suppression of capillary adhesion
Friction originates at the area of real contact which depends on the (changing) surface topography. Observing and measuring the area of real contact at multi-asperity interfaces is difficult, making it challenging to quantitatively study the interplay between the frictional force and surface topogra...
