dc.description.abstract | The degradation kinetics of gamma radiolytically synthesized Ag-PVA nanocomposites was investigated by thermogravimetric method under dynamic conditions (30-600 degrees C) in an inert atmosphere. Thermogravimetric analysis showed that thermal degradation of composites was a two-stage process for the lower amount of nanofiller and single-stage for the higher amount of nanotiller. The Vyazovkin model-free kinetics method was applied to calculate the activation energy (E-a) of the degradation process as a function of conversion and temperature. At a given degradation temperature, PVA as a host in nanocomposite presents lower reaction velocity, while its E-a is higher than that of pure PVA. (c) 2007 Elsevier B. V. All rights reserved. | en |
