INVESTIGATION AND ESTIMATION OF INTERFACE ENERGY CHARACTERISTICS

A new equation has been obtained for calculating the equilibrium contact wetting angle on the basis of the capillary constant evaluated from the shape of a real droplet of liquid on a solid surface. The value of the surface tension of liquid is determined experimentally using the geometric parameters of the liquid droplet on a solid surface. The proposed equations make it possible to determine the equilibrium contact wetting angle of the solid body surface with thermodynamic parameters σ_liq–g, σ_s.b–liq and σ_s.b–g on the interface between three phases: solid body–liquid–gas.
