This report describes the synthesis and some properties of hybrid Poly (acrylonitrile) – silica nanocomposites having potential as chromatography sorbents. The focus is on the fact that the properties of such nanostructures can depend not only on the chemical nature of their components, but also on the synergy of these components. The sol–gel approach involved the hydrolysis and condensation of tetraethoxysilane, with smaller amounts of acrylonitrile polymerized in such a way as to generate polymer dispersed in the continuous silica phase. The resulting polymer–modified silica materials were characterized by infrared spectroscopy, scanning electron microscopy and chromatographic analysis.
