To investigate the decay mechanisms of red oak (Quercus rubra) and hemor (Schima spp.) woods in the old architectural structure of Xichuan Guild Hall, chemical composition changes were determined and analyzed with X-ray photoelectron spectroscopy (XPS). The results showed that decaying resulted in a noticeable decrease of the O/C from 0.59 to 0.42 in the red oak wooden components. The increase of C1 contribution, decrease of C4 contribution, increase of O1 and O3 contributions, and decrease of O2 contribution indicated that the carbohydrates in red oak wooden components can be easily degraded by fungi compared with lignin. Moreover, decaying resulted in a slight decrease of the O/C from 0.49 to 0.47 in the hemor wooden components. The results of increase of C1 contribution, decrease of C3 and C4 contributions, increase of O1, and decrease of O2 and O3 contributions indicated that carbohydrate and lignin were all degraded by fungi.

Strong, durable, and aging-resistant bamboo composites were prepared by silver electrochemical and high-voltage electrostatic field (HVEF) treatments. Surface morphology, chemistry, and wettability were investigated after the treatments. Changes of rheological and curing characteristics of resin were determined. After preparation, the aging resistance and mechanical properties of bamboo composites were tested. The results showed that under the HVEF treatment, silver interacted with hemicellulose and lignin of bamboo and nanosized silver particles distributed evenly on the surface of bamboo. On the other hand, nanosilver particles directly interacted with the molecular chain of the resin by strong physical/chemical forces. According to the chemical and rheological results, the cross-linking degree of phenolic resin was proved to be increased by the catalysis of silver. An increment of density along the bonding line as well as mechanical properties of the composites was found. These findings prove that silver electrochemical and HVEF treatments are effective to regulate the structures and properties of bamboo composites and may also be relevant to the development of new bamboo engineering composites.
