Surface and colloidal properties of hydrosilane-modified Stöber silica
Abstract
Triethoxysilane (TES), HSi(OEt)3, was used to functionalize Stöber silica and the resulting particles were characterized in acetone and water by light scattering, disk centrifugal photosedimentometry, microelectrophoresis, transmission electron microscopy, and 29Si CP-MAS and 1H MAS NMR spectroscopy. The thickness of the polymerized TES layer on the silica surface was found to be dependent upon the concentration of the TES solution used. Thus, …
