Abstract
Stabilization of the properties of epoxy materials in response to ionizing radiation is an important task for predicting the service life of the product. This study investigated the effect of γ-radiation on the structure and mechanical and thermal stability of epoxy nanocomposites with TiO2 nanoparticles (n-TiO2). The oxidation of epoxy chain bonds at doses above 42 kGy was shown using IR spectroscopy. The addition of n-TiO2 makes it possible to increase the strength and strain and also stabilize the mechanical and thermal properties of the composite with respect to γ-radiation.
