摘要：

The objective of this study was to investigate the effects of a functional wood modifier (ureaformaldehyde prepolymer) on fast-growing wood. Physical and mechanical properties and mainly chemical components were tested. Thermo-gravimetric analysis (TG) resulted in improvement thermal stability of the modified composites. The durability against fungus was examined and weight loss reached 6.16 % after modification. The Fourier Transformed Infrared Spectroscopy (FTIR) spectroscopy showed the chemical changes in wood after modification and illustrated the modified mechanism. Finally, Scanning Electron Microscope (SEM) and Energy Dispersive X-Ray Analysis (EDXA) micrographs presented the distribution of wood modifier in cell wall.
