Our results suggest that suitable liquids for determining the values of disperse component γSV d of wood surface free energy are apolar liquids (in our case α-bromonaphtalene or diiodomethane); and for polar component γSV p apolar-polar liquids with the polar component bigger than the polar component of wood (in our case water). The wood surface free energy gSV representing the sum of the disperse and polar component γSV d and γSV p obtained in this way is higher than the wood surface free energy determined with one liquid only. Wood moisture content has been confirmed as an important factor influencing the parameters of wetting process as well as the values of surface free energy and its components. With increasing wood moisture content, the period for reaching the equilibrium tu was prolonged, contact angles increased in all experimental variants and surface free energy decreased over the whole moisture range.
