Inorganic-organic proton-conductive composites were fabricated by Use of the sol-gel process and evaluated with various characterization. Enhancement in ionic conductivity and mechanical property was expected by the formation of phase separation in meso-scale size. Silicon based organic compounds and silicate were employed as the starting materials. The main results obtained in this study are summarized as follows ;1.Micro-scale phase separation was observed in the samples containing siloxane.2.The samples consisted of three parts, namely soft phase, hard phase and interface phase.3.The phase-separated samples showed enhanced proton conductivity when a solid acid was added.4.The mechanical strength was not so large but influence of interfacial connection of separated phases were suggested.5.The role of water in the phase-separated samples was thought to be one of the important factor to dominate the electrical and mechanical properties.

采用溶胶-凝胶法制备了无机-有机质子导电复合材料，并对其进行了表征。在介观尺度上形成相分离有望提高离子电导率和力学性能。硅基有机化合物和硅酸盐被用作起始原料。本研究取得的主要成果概括如下：1.在含正庚烷的样品中观察到了微尺度的相分离。2.样品由三部分组成，即软相，硬质相和界面相。固体酸的加入使分离样品的质子传导率提高。4.分离相的机械强度不是很大，但界面连接的影响很大。5.水在分相样品中的作用被认为是控制电性能和机械性能的重要因素之一。
