Sažetak
Degradation kinetics of organic-inorganic hybrids based on epoxy resin was investigated by thermogravimetric analysis (TGA). The hybrid materials were prepared from diglycidyl ether of bisphenol A (DGEBA) as organic precursor, and 3- glycidyloxypropyltrimethoxysilane (GLYMO) as inorganic precursor, polymerised simultaneously by poly(oxypropylene)diamine (Jeffamine D230). Energy of activation (Ea) of degradation processes for the hybrids with varying inorganic content, as well as for the unmodified epoxy-amine system, was determined by isoconversional Kissinger-Akahira- Sunose method. The complete process of degradation was described by empirical kinetic models. It was found that the hybrid materials have significantly higher Ea of degradation than the unmodified epoxy-amine resin, and that the inorganic network influences the mechanism of degradation of organic phase. Thermal stability of hybrid materials was confirmed by other parameters obtained by TGA.
