Abstract


In this study, the effect of a therapeutic dose of gamma irradiation used, for example, in cancer treatment, on the thermal and structural properties of polycaprolactone/gypsum composite films (PCL/Gesso Cs) was evaluated. The composite films (Cs) were obtained by the solvent evaporation method, using chloroform as a solvent, and were irradiated at 140 Gy in the presence of air at room temperature. Then the films were characterized by experimental techniques such as: Infrared Spectroscopy (FT-IR), Thermogravimetric Analysis (TGA), X-Ray Diffraction (DRX) and Scanning Electron Microscopy (SEM). Previous results demonstrated that gamma irradiation at the evaluated dose changed the thermal properties of composites.
