摘要：Silicon sol solution was introduced into poplar wood by vacuum-pressure impregnation process, and a series of composites with different weight percent of gain (WPG) were prepared. The structure and properties of the untreated and composite wood were investigated. Compared to untreated wood, composite wood had a promising potential to improve mechanical properties like bending strength, modulus of elasticity and surface hardness. SEM pictures of composite wood with 30.3 WPG showed that the SiO2 gels filled the pores of the wood but unchanged the structure and morphological arrangement. TG and contact angle results indicated that composite wood showed an improved thermal property and water repellent property, and those properties increased with increasing of WPG. ?
