Abstract: X-ray photoelectron spectroscopy (XPS) is one of a set of tools that have been used to characterize wood surfaces. Among the advantages of XPS are surface sensitivity, identification of nearly all elements, and frequently, discrimination of bonding states. For these reasons, XPS seemed to be an appropriate tool to help explain the differences in bond strength under wet conditions for planed and unplaned acetylated wood bonded with epoxies. Some care needs to be taken to ensure correct analysis of the high-resolution XPS spectra. The XPS, in conjunction with labeling with trifluoroacetic anhydride, was used to characterize the extent of acetylation at cellulose and wood surfaces. These results led to the conclusion that the trifluoroacetic anhydride labeling was a useful method for characterizing reactable cellulosic hydroxyl groups and that planing the acetylated wood exposed additional unmodified hydroxyl groups.
