It is well known that elastomer surfaces vary friction behavior with the sliding conditions. These frictional characteristics depend on interfacial dissipation of viscoelastic asymmetric deformation and adhesion. As adhesion plays a dominant role in such friction behavior at very low sliding velocities, adhesive friction of elastomer is focused and discussed. The one mechanism of adhesive friction force generation is macroscopic dissipation of fracture and healing of contact junction. The other one is microscopic dissipation of attachment and deformation of molecular chain of elastomer. It is shown that the combination of these two mechanism can explain the friction characteristics at very low speed conditions.
