| 摘 要： | 采用甲基三乙氧基硅烷(MTES)与正硅酸乙酯(TEOS)共水解获得改性溶胶，然后将溶胶通过真空-加压设备浸注入木材内部，并发生凝胶复合制备陶瓷化木材，解决了TEOS水解溶胶制备的陶瓷化木材脆性大、耐水性差的问题。改性凝胶具有疏水性，降低了陶瓷化木材的吸水增重率，提高了抗压和抗弯曲强度等力学性能。

| Abstract: | Wood-ceramic composites which demonstrate some unique characteristics have attracted scientists' research attention lately.A modified sol prepared through the methyl triethoxy silane(MTES) hydrolysis process was impregnated into the wood cells with vacuum-pressure cycles.The alternate pressure cycles overcame some barriers of slow and incomplete impregnation that the previous processing method presented.The results indicate that wood-ceramic composites made with the METS modified sol through the alternate p... |
