    • The present invention relates to compositions of matter comprising polyhedral structural units of empirical formula Si2O3, with silicon atoms at the vertices of the polyhedron and oxygen atoms at the center of each edge, arranged in an ordered manner with a repeat distance characteristic of such order in the range of 1 to 2 nanometers and organosilicon crosslinking groups tying these units together to form a polymeric material that exhibits Bragg reflection peaks in the X-ray region of the electromagnetic spectrum. The present invention further relates to methods of preparing such compositions. The nanocomposite materials according to the invention may be useful, for example, as electronics packaging materials, as resists for e-beam lithography, as protective coatings, as binders for refractory sands, as the matrix in polymer matrix composites and as reflective materials in soft X-ray telescopes and microscopes.
    • 本发明涉及包含经验式Si 2 O 3的多面体结构单元的物质组合物,其中多面体顶点的硅原子和每个边缘中心的氧原子以有序的方式排列,具有这种顺序的重复距离特征 1至2纳米的范围和有机硅交联基团将这些单元结合在一起以形成在电磁光谱的X射线区域中显示出布拉格反射峰的聚合物材料。 本发明还涉及制备这种组合物的方法。 根据本发明的纳米复合材料可以用作电子包装材料,作为电子束光刻的抗蚀剂,作为保护涂层,作为耐火砂的粘合剂,作为聚合物基质复合材料中的基体,以及作为柔软的反射材料 X射线望远镜和显微镜。
