Structure of random porous materials: Silica aerogel
Journal Article
·
· Phys. Rev. Lett.; (United States)
Using small-angle x-ray scattering, we show that porous silica aerogel has a fractal backbone structure. The observed structure is traced to the underlying chemical (polymerization) and physical (colloid aggregation) growth processes. Comparison of scattering curves for aerogel with silica aggregates confirms this interpretation.
