Surface properties of wood are important for both wettability and hydrophobic modification.
Glueability of wood is related to wettability, while durability and decay resistance are
affected by physical and chemical components. This review (Part I) discusses hydrophilic
characteristics of surfaces. Surface theories, calculation methods for surface tension,
topography, contamination, and aging are reviewed. It was found that surface tension data
were often disparate; a standardized procedure for contact angle measurement would …
