Summary
Mathematical models for the polar and dispersion force contribution to the total surface free energy of a solid are reviewed. Experimentally, the geometric-mean and harmonic-mean models are compared for the surface of Douglas-fir wood. Data for both models compare favourably with results from the literature for other man-made and naturally occurring polymeric surfaces. Arguments are offered favoring the use of the harmonic-mean model for characterizing the surface of wood.
