Nanocomposite Organolithic Macromolecular Material with Long-Range Structural Order

摘要

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.
