Description	Organic/inorganic hybrid networks were prepared by a novel solvent-free two-step synthesis method. In the first step, prehydrolyzed–condensed reactive inorganic precursors (clusters) were prepared by a sol–gel process from monomeric alkoxysilanes with amino and glycido groups. The second step comprised their addition into epoxy resin and amine hardener, followed by the reaction of all components giving the final hybrid crosslinked materials. The morphology of the organic/inorganic hybrid structures formed from glycidoprecursor revealed spherical silica-rich domains forming agglomerates with diameter from 100 to 500 nm. The aminoprecursor led to large highly condensed and branched silicon-rich structures. The hybrid networks showed significantly improved thermomechanical properties and better resistance against thermooxidation when compared with the neat epoxy–amine network. Thin films as well as bulk materials were successfully prepared by this process. Organic/inorganic hybrid networks were prepared by a novel solvent-free two-step synthesis method.
