Abstract
Dynamic contact angle (DCA) analysis, utilizing the Wilhelmy plate method of contact angle measurement, was used to study the dynamic wettability of red oak (Quercus rubra) and yellow-poplar (Liriodendron tulipifera). The effects of wood elemental and chemical composition, surface roughness, absorption and capillary flow, sample aging, and machine testing speed were examined. DCA analysis appears to be a useful method for studying the dynamic wetting behavior of wood, and when combined with X-ray photoelectron spectroscopy (XPS) and wood chemical composition data, it provides information regarding how wood processing and environmental conditioning effects surface energetics and chemistry.
