Hybrid nanocomposite materials based on oxide nanoparticles incorporated in polymer matrix have been extensively studied in the last two decades. The purpose of the investigation was to study the ability of these materials to withstand radiation environments such as those encountered in nuclear power plants. Two nanocomposite polymers have been developed and characterized. They are based on a P(VDF-TrFE) matrix filled with either ZnO nanoparticles or Al2O3 nanoparticles. All nanocomposites were irradiated with two different types of particles (neutron and X-rays). For such materials, Brillouin spectroscopy can provide information on both elastic and elasto-optic variation with the radiation dose. This research points out that this technique also provides a good diagnostic of chemical and structural modifications induced by radiations.
