Popis: Changes in the work of adhesion γSL of polar and nonpolar liquids, as well as the dispersion and polar components of the surface energy of γS suspension-polymerized polytetrafluoroethylene (PTFE) as a function of the gamma-radiation dose are analyzed quantitatively. A physicochemical model for increasing the work of adhesion γSL of a polar liquid is proposed. The model is based on the formation of a double electrostatic layer at the phase interface due to ion-dipole interaction.
