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.

通过使用溶胶 - 凝胶工艺制造无机有机质子传导性复合材料，并以各种表征进行评估。通过在中尺度大小中形成相位分离，预计离子电导率和机械性能的增强。基于硅的有机化合物和硅酸盐被用作起始材料。在本研究中获得的主要结果总结如下：1。在包含硅氧烷的样品中观察到微尺度的相分离。2。样品由三个部分组成，即柔软相位，硬相和界面相。3。相位分离的样品。添加了固体酸的质量分离，但ph sy ph s s of the Mative ph per n.44.相位分离的样品被认为是主导电气和机械性能的重要因素之一。
