We review the adhesion fundamentals and related physical aspects occurring from the nanoscale up to the length scale of macroscopic interacting solids. In particular, we provide theoretical basis for predicting surface and adhesion energies at the atomic scale, where adhesion originates, as well as the most relevant experimental techniques for the quantitative evaluation of the work of adhesion. The role of non-equilibrium processes, as well as of mesoscale interaction dynamics, will be assessed in term of the resulting adhesion regimes at the macro-scale. Mean field and numerical models are finally provided for the prediction of adhesion between real solids, in order to determine macroscopic physical quantities such as pull-off force and true contact area.

Abstract
We review the adhesion fundamentals and related physical aspects occurring from the nanoscale up to the length scale of macroscopic interacting solids. In particular, we provide theoretical basis for predicting surface and adhesion energies at the atomic scale, where adhesion originates, as well as the most relevant experimental techniques for the quantitative evaluation of the work of adhesion. The role of non-equilibrium processes, as well as of mesoscale interaction dynamics, will be assessed in term of the resulting adhesion regimes at the macro-scale. Mean field and numerical models are finally provided for the prediction of adhesion between real solids, in order to determine macroscopic physical quantities such as pull-off force and true contact area.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
