In the aspects of research method, we took the method of preparing sol at first and then impregnating the wood to obtain ceramic-wood composite; this method made the wood use efficiently and increased the wood's weight gain percent. The ceramic-wood composite with performances of well decay resistance, dimensional stability, effloresce resistance and high strength was obtained by importing the cymene to the net of gel as the result of co-hydroxylation between MTES and TEOS. Making use of XPS ,we found that the apex of Si2p亚洲国产精品无码久久、O1s、C1s had evident chemical shift , which validated the existence of Si-O-C bonding.Key Words: Sol-gel, Ceramic-wood composite, Modified sol, Ecomaterials
