Functional Group Distributions on Mesoporous Silica

CHIMIA, 2011
Most applications of mesoporous silica require some degree of functionalization. The surface of porous materials can be divided into external and internal (pore) surfaces, and in many cases, a selective functionalization of these surface subsections is desired.

Remarkable enhancement of thermal stability of epoxy resin through the incorporation of mesoporous silica micro-filler

Heliyon, 2021
For the first time, we incorporated mesoporous micro-silica (5 μm, pore size = 50 nm) as a filler in epoxy resin aiming to enter polymer into the pore of the silica.

Monodispersed mesoporous silica spheres with various mesopore symmetries

Journal of Colloid and Interface Science, 2014
Monodispersed mesoporous silica spheres (MMSS) with different mesopore symmetries, such as hexagonal, cubic, or the mixture of hexagonal/cubic, are synthesized changing synthesis conditions. It seems that the direction of mesopores is retained through the particle in MMSS with cubic symmetry.
