Effects of progressive changes in organoalkoxysilane structure on the gelation and pore structure of templated and non-templated sol–gel materials

Hydrolysis–condensation reactions of diethylphosphato-ethyltriethoxysilane with tetraethoxysilane studied by 29Si-NMR: Solvent and phosphonate catalytic effect

“…The results show that depending on the trialkoxysilane component, the polycondensation reaction could be quickened or the gelation time delayed. These phenomena were also evidenced by Mah et al [13] in the case of the addition of various amount of dimethyldiethoxysilane with TEOS as well as the effects of progressive changes in the organoalkoxysilane structure on the gelation and pore structure of solgel materials [14]. The distribution of methyl groups in silica gels was observed by Witte et al [15] from mixtures of TEOS with methyltriethoxysilane and dimethyldiethoxysilane, respectively.…”

Mesoscopic Patterning in Evaporated Polymer Solutions: Poly(ethylene glycol) and Room‐Temperature‐Vulcanized Polyorganosilanes/‐siloxanes Promote Formation of Honeycomb Structures

“…On the one hand they stimulate water absorption on the surface of the evaporated polymer solution. On the other hand, as it was established recently, polyorganosilanes (methyltrimethoxysilane) promote the well‐defined porosity of the eventual sample when used in sol/gel processes 55, 56. Recent work by Evmenenko et al devoted to interfacial ordering in polysiloxane films is also noteworthy 57.…”

Materials engineering for surface-confined flame retardancy

“…These alkoxysilanes can be introduced covalently into an inorganic metal oxide network. The organic group can act simultaneously as a network modifier that changes properties of the resulting coatings such as the porosity [129]. Hydrophobic or even oleophobic surfaces can be designed by introducing alkyl-or fluoroalkyl groups into the coating material [130,131].…”
