摘要：

No single technique has been universally satisfactory for determining the wettability of wood. The objective of this study was to determine the change in wettability of weathered wood using a videotape technique for determining contact angles. Contact angles of water on western redcedar and southern pine panels were determined after 0-12 weeks of outdoor weathering. Contact angles were calculated by computer on 'frozen' images of drops displayed from videotape recordings. Wettability of western redcedar increased with time of weathering, as shown by progressively decreasing contact angles. Contact angles increased during the early portion of weathering of southern pine, but decreased steadily thereafter. The conservative Tukey test was used to show which values are significantly different.
