The results indicated that hydrogen bond and covalence bond were formed between PVA and TEOS through the sol-gel reaction.

结果表明PVA与无机相发生溶胶-凝胶反应生成氢键和共价键Si-O-Si，形成交联有机聚合物／无机杂化体系，使杂化膜的结晶度减少，控制了膜的溶胀，提高膜的溶解选择性能，但膜的溶胀减少会使通量有所下降。

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、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

在工艺方法上，采用先制备溶胶，然后浸注木材的工艺方法具有原料利用率高、提高增重率的优点；采用甲基三乙氧基硅烷和正硅酸乙酯共水解的方法，将甲基引入陶瓷化复合木材的凝胶内部，所制备的材料具有尺寸稳定性好、具有耐风化和耐腐朽性，强度高的特点；首次利用X射线光电子能谱，发现了Si2p、O1s和C1s谱峰发生了明显的化学位移，证实了Si－O－C键合作用的存在。

From the transform infrared spectroscopy and X-ray photoelectron spectroscopy spectra, the hydroxyl and ethoxyl groups of the silica sol drawn from partially hydrolysis and polycondensation between TEOS and MTES can react with PA6 precursor.

红外图谱和X射线光电子能谱分析结果显示，硅溶胶的羟基和未完全水解的烷氧基能够与PA6的前驱体发生杂化反应。X射线衍射结果显示，采用本实验方法制备出的PA6和疏水型PA6/SiO2有机无机杂化材均为α晶型，而DSC结果表明，PA6/SiO2有机无机杂化材料的熔点略高于PA6。

The anti-oxidation effect is not remarkable when the composite is alone pre-impregnated in HBO2 or TESO soaker. The anti-oxidation property is good for the composite pre-impregnated in H3PO4 or H3PO4+HBO2 mixed solution soaker. The mass loss rate oxidated at 900℃ for 2h are 0.40% and 0.33% respectively.

单独预浸涂以硼酸或TEOS为主的浸渍剂后，试样抗氧化效果不明显，而预浸涂以磷酸或磷酸+硼酸混合液为主的浸渍剂效果较好，900℃，2h静态氧化质量损失率分别为0.40%和0.33%。

He velocity of hydrolyzing and polymerizing of TEOS is in relation with the value of water, acid, and temperature.

EOS的水解和聚合速度主要与体系的用水量、酸的浓度和酸种类、操作的温度等有关。
