patent number 8491815
Disclosed are bulk, crosslinked nanocomposite networks that do not require a host polymer in the matrix. Bulk nanocomposites can be formed via derivatization of nanoparticles with functional ligands that directly or indirectly crosslink with one another or with nanostructures of the network to form a highly crosslinked network. Disclosed bulk nanocomposites can contain nanoscale materials at extremely high loading levels. Nanostructures incorporated in the networks can include optically active materials such as inorganic nanostructures doped with optically active rare earth ions.
