Abstract

The development of photoactive polymer materials resistant to external impacts for use under conditions of exposure to intense light and high temperatures is an urgent problem. This study is focused on the effect of ultraviolet irradiation on the structure and thermophysical properties of epoxy nanocomposites based on the ED-20 epoxy resin cured with 4,4’-diaminodiphenylmethane and triethylamine. Using UV–Vis spectrophotometry, IR spectroscopy, X-ray diffraction analysis, and calorimetric studies, it has been shown that the introduction of titania nanoparticles in an epoxy polymer leads to an increase in the UV resistance of the matrix.
