【摘要】 溶胶一凝胶法作为温和条件下合成无机材料的重要方法,在制备玻璃、陶瓷、薄膜、纤维、纳米粒子、复合材料等方面获得重要应用。基于二元酸草酸与氨丙基硅氧烷为前驱体超分子作用,制得具有层状结构的产物。以此为起始物,获得了不同条件下的有机无机复合材料。利用扫描电镜、红外光谱、热重分析和XRD等手段对所制得的复合材料进行了表征。结果表明,该复合材料整体呈球形,表面呈现由片层结构组成的复杂结构。更多还原

【Abstract】 Sol-gel method,as a mild procedure for the synthesis of inorganic materials,has been applied abundantly at glass,ceramics,films,fiber,nanoparticles and complex materials fields.In this study,the composite materials were prepared by the sol-gel process from the aminopropyltriehoxylsilane precursor, along with oxalic acid as template.The morphology,composition and crystalline of the composite particles were characterized by SEM,IR,TGA and XRD.The results demonstrated that the composite materials had a whole spherical framework diameter of 5-6 micrometer.更多还原
