Surface Free Energy of Boron-Compounds Modified Poplar Veneer

Abstract:

The contact angle of three different reference liquids (i.e. distilled water, diiodomethane, and formamide) was measured by the sessile drop method by gently placing droplet onto the surface of the boron-compounds treated poplar veneer in this study. The permeability of the modified poplar veneer was evaluated. The surface free energy, as well as two components, namely, Lifshizvander Waals(LW) and Acid-base(AB), were calculated by the Acid-base theory, whereas the polar and nonpolar components were calculated according to the OWRK theory. The result shows that the initial contact angle of boron-compounds modified poplar veneer are significantly less than the untreated wood, which indicates that the wettability of boron-compounds polar veneer is better than the untreated wood. The same situation applies to the permeability. In addition, the surface free energy of boron-compounds modified poplar veneer is reduced, but the difference is very small.
