Furthermore, if two surfaces interact weakly, the contact angle is large; if two surfaces interact strongly, the contact angle is small. For example, the energy of binding of gold adatoms with the graphite substrate is of order 0.45 eV/atom, and the contact angle between gold nanoparticle and graphite substrate is 129. The interaction between gold and tungsten is as high as 3.3-4.1 eV/atom, and the contact angle between gold nanoparticle and tungsten substrate is 63.

Furthermore, if two surfaces have weak interaction, the contact angle is large. On the contrary,  if they have strong interaction, the contact angle is small. For example, the binding energy of gold adatoms with the graphite substrate is of an order of 0.45 eV/atom, and the contact angle between the gold nanoparticle and the graphite substrate is 129. Interaction between gold and tungsten is as high as 3.3-4.1 eV/atom, and the contact angle between the gold nanoparticle and the tungsten substrate is 63.
