Head Mikhalchuk V.M., Registration Date 19-05-2005 Organization Donetsk National University popup.description2 Object of research - hybrid composite materials on a basis of alkoxysilanes and epoxy resins. The purpose of work - studying of influence of composites composition on kinetics structurizations and properties of organic-inorganic polymers. Methods of research - spectrophotometrical, differential microcalorimetry, gasolumo-metrical, a chemical method of the analysis. Results - capabilities of use sol-gel technology in epoxy olygomer directly and in the inert solvent environment for reception of epoxy-inorganic polymers with use alkaline and acid catalysis hydrolysis of alkoxysilanes are investigated. Influence of alkoxysilanes ratio, concentration of the hydrolysis catalyst, the nature of organic solvent, epoxy resins and its concentration on sol formation process is investigated. Concentration of the basic components which provide reception of stable at preservation sols, and also reception of transparent organic-inorganic gels are determined. It is established, that at carrying out of sol-gel process in situ at presence epoxy resins is slowed down hydrolysis and the following sol formation. Change of concentration of an inorganic phase and solvent allows to change rate of formation organic (epoxy) polymeric network in wide ranges.
