The thermal stability of organic-inorganic composites prepared by a twostage
polymerization of urea-formaldehyde resin (UF) with micro- and
nano-TiO2 before and after irradiation has been investigated. Composites of
urea-formaldehyde and particles of TiO2 of different size were synthesized,
namely: Composite 1 (UF+ micro-TiO2) and Composite 2 (UF + nano-
TiO2). The thermal stability of obtained materials was studied by nonisothermal
thermo-gravimetric analysis (TG), differential thermal
gravimetry (DTG) and differential thermal analysis (DTA). Hybrid
composites based on UF resin have been irradiated (50 kGy) and after that
their radiation stability was evaluated on the basis of thermal behavior. DTG
peaks of both composites are shifted to a higher temperature after
irradiation, but Composite 1 after irradiation shows less change in thermal
behavior than Composite 2.
