Abstract
Introducing a desired solid guest to nn about-to-gel silica sol prevents I complete encapsulation of the guest particles by the silica, such that the composite retains the bulk and surface properties of each component on the nanoscale. The transport- and density-dependent properties of the composite aerogel call be tuned by varying the volume fraction of the second solid, thereby increasing the design flexibility of these nanoscale materials for optical, chemical, thermal, magnetic, and electronic applications. The chem ical and physical properties of the composite material can be further engin eered at multiple points during sol-gel processing by modifying the host so lid the guest solid, the composite gel, or the composite aerogel.
