It is useful to know the scale of lengths over which the adhesion interactions as described above do occur (Table 2.2) [21]. It is apparent from Table 2.2 that the adhesive interactions relying on interlocking or entanglement can occur over larger lengths than the adhesion involving charge interactions. Most of the charge interactions occur at the molecular level or the nano-length scale. Electrostatic interactions are the exception to this generalization. For the purpose of adhesive interactions, they are considered to operate from a nano- to a micron-length scale.
