Physical and chemical regularities of creating new hybrid epoxy polymer nanocomposites with increased strength characteristics

By the method of pK-spectroscopy the acid-base properties of the surface of oxides of aluminium, iron, silicon are investigated. Physical and chemical regularities of the reactions between epoxy oligomers and modified fillers are studied. Higher reactivity of γ-Al2O3 and γ-AlO(OH) is observed due to the presence of the most active surface groups with pK1≈ 4. Substantiation for increasing the strength characteristics of hybrid epoxy polymer nanocomposites is given.
