Adhesional wetting

  "id": "MLC-T-CHM-000248",
  "term": "Adhesional wetting",
  "field": "Chemistry",
  "definition": "A wetting process in which a liquid drop or film is brought into contact with a solid so that an adhesional joint forms, replacing the solid-vapour and liquid-vapour surfaces over the contact area by a solid-liquid interface. The Gibbs energy change equals minus the work of adhesion, which is the sum of the two surface tensions minus the solid-liquid interfacial tension. It is distinct from spreading wetting, where the liquid also extends over new area, and from immersional wetting.",
