Dispersion-Polar Surface Tension Properties of Organic Solids

A new definition for work of adhesion Wa is applied to computationally define the dispersion γs d and polar γs d components of the solid surface tension γs = γs d + γs d for twenty-five low energy substrates. These calculated surface properties are correlated with surface composition and structure. Surface dipole orientation and electron induction effects are respectively distinguished for chlorinated and partially fluorinated hydrocarbons. Published values for critical surface tension of wetting γc are correlated with both γs d and γs.
