Abstract:In
this work, we examined the effect of nanoparticle
size on the
thermal conductivity of mesoporous silica materials made from colloidal
precursors. Porous thin films were synthesized using a polymer-templating
method, employing commercial colloidal silica solutions containing
nanoparticles 6, 9, and 22 nm in diameter as the silica source and
poly(methyl methacrylate) colloids as the template. The ratio of polymer
to silica was then varied to produce films with a range of porosities.
The thermal conductivity o… Show more
