| 摘 要： | 以正硅酸乙酯(TEOS)、甲基三乙氧基硅烷(MTES)、聚乙烯醇(PVA)为原料，基于溶胶凝胶工艺制备出疏水型多孔PVA／SiO2有机无机杂化材料。杂化材料内部的硅氧链与PVA链相互交织，形成杂化网络结构，具有增强增韧的效果。杂化材料在热处理过程中，小分子逸出产生的微孔和材料表面面外的甲基，赋予了材料的透气疏水性能，可用于制备性能优良的环保型包装薄膜、农用地膜等功能复合材料。

| Abstract: | Tetraethoxysilane (TEOS), methylethoxysilane (MTES) and polyvinyl alcohol were used to synthesize hydrophobic and multipore PVA/SiO_2 organic-inorganic hybrid material based on sol-gel method. The crosslinked Si-O-Si units and PVA chains in hybrid material form organic-inorganic hybrid networks and produce reinforcing and toughing effects. Moreover, The outstretched methyl groups on the surface and the multipores in the body contribute hydrophobicity and air permeability. This hydrophobic and multipore PVA/SiO_2 organic-inorganic hybrid material can be used to prepare functional composite materials such as environmentally-friendly packaging film and mulching film etc.. |
