Abstract—Exposure to ionizing radiation has been found to induce changes in poly(vinylidene fluoride) (PVDF) homopolymers.
The high dose gamma irradiation process induces the formation of C=C and C=O bonds in its [CH2-CF2]n main chain. The irradiation
also provokes crosslinking and chain scission. All these radioinduced defects lead to changes in the PVDF crystalline structure. As a consequence, it is common to observe a decrease in the melting temperature (TM) and melting latent heat (LM) and some changes in
its ferroelectric features. We have investigated the possibility of preparing nanocomposites of PVDF with graphene oxide (GO)
through the radio-induction of molecular bonds. In this work, we discuss how the gamma radiation interacts with the nanocomposite
crystalline structure
