Thermal stability, degradation kinetic and electrical properties studies of decorated graphene oxide with CeO2 nanoparticles-reinforced epoxy coatings: Fullerenes, Nanotubes and Carbon Nanostructures: Vol 29, No 6

Summary

We synthesized adorned graphene oxide with CeO2 nanoparticles (CeO2-GO) hybridusing silane coupling brokers, then we dispersed them within the epoxy resin after optimizing it at a weight fraction %1 utilizing differential scanning calorimetry (DSC). The structural and morphological characterization was evaluated utilizing Fourier Remodel Infrared spectroscopy (FT-IR), scanning electron microscopy (SEM) and X-ray diffraction. The thermal stability of CeO2-GO/Epoxy (CGE) and neat epoxy (NE) have been studied by TGA analyses and confirmed that the CGE system has an excellent thermal stability and better char yield evaluating to the NE system. The degradation kinetic parameters for CGE matrix have been computed by the Vyazovkin’s superior isoconversional technique. The grasp plots as mannequin becoming was used to estimate the thermal decomposition mechanism, and the outcomes present an excellent settlement between the experimental knowledge and the F1 theoretical mannequin. We have now used electrical impedance spectroscopy (EIS) to judge electrical resistance of the CGE system at completely different % of (CeO2-GO) nanoparticle. This analysis highlights that the (CeO2-GO) nanoparticleis a promising candidate for fabrication of anticorrosive coatings.
