A type of TiO2/bamboo charcoal composite made by a dip-dry method was loaded onto wood veneer with a vacuumpressure method in order to prepare modified poplar veneer.The pore structure parameters and surface morphology of the TiO2/bamboo charcoal composite were determined and analyzed by means of a porosimetry analyzer and SEM.The results show that the surface morphology of the composite does not change after being loaded with nano TiO2.However,its specific surface area (359.814m2·g -1),pore volume (0.317 cm3·g-1) and average pore diameter (3.526 nm) increased; particularly the cumulative volume of pores was increased by 65.83％.In addition,the distribution range of the pores was wider than that of the bamboo charcoal.Combining the SEM of unmodified and modified poplar veneer,the results of X-ray photoelectron spectroscopy revealed that actually some TiO2 compounds,i.e.,4.08％,are imbedded in the modified poplar veneer.
