Abstract
A composite material that includes a dopant comprised of pre-formed, three dimensional assemblies of skeletal structures that are comprised of solgel derived nanoparticles. The composite material includes a chemically bonded, in situ formed, polymer coating that at least partially coats mesoporous surfaces of the nanoparticles to provide enhancement of random dispersion of the dopant and to minimize or avoid agglomeration. Further, the polymer may be functionalized or the mesoporous surfaces of the nanoparticles may be treated to enable stronger chemical bonding between the dopant and the polymer.
