The structural properties of epoxy-silica nanocomposites of anhydride curing synthesized by the sol-gel method were studied using small-angle X-ray scattering and electron microscopy. It was shown that the aggregation processes change significantly during the formation of sols of silica nanoparticles (SP) by using 3-glycidoxypropyltriethoxysilane (GPTES) in the presence and absence of an epoxy oligomer in the system. The fractal aggregate types of each structural level are identified and their sizes are determined by the fractal analysis. It was found that there is a two-level and three-level fractal organization for GPTES-based sols, formed in the presence of an epoxy oligomer, depending on the content of SP. At the same time, aggregates with an average size of 10-11 nm are formed at the first structural level; SP form aggregates with an average size of 65-70 nm at the second level, while the size of the third-level aggregates is more than 250 nm.

使用小角X射线散射和电子显微镜研究了溶胶-凝胶法合成的酸酐固化环氧-二氧化硅纳米复合材料的结构特性。结果表明，在系统中存在和不存在环氧低聚物的情况下，通过使用 3-环氧丙氧基丙基三乙氧基硅烷 (GPTES)，在二氧化硅纳米粒子 (SP) 溶胶的形成过程中，聚集过程发生了显着变化。每个结构层次的分形聚集体类型被识别，它们的大小由分形分析确定。发现基于 GPTES 的溶胶存在两级和三级分形组织，在环氧低聚物存在下形成，这取决于 SP 的含量。同时，在第一结构层面形成平均尺寸为10-11nm的聚集体；
