Abstract
Monodisperse colloidal silica spheres were prepared from tetraethylort hosilicate in mixtures of water, ammonia and ethanol. The surfaces of the spheres were successfully modified by chemical reaction with silan e coupling agents. Several qualitative and quantitative methods were e mployed to analyse the organic surface modifications. As a result, the surface coverage of silica spheres with silane coupling agents could be calculated using different characterization methods.
