Effect of non-covalent functionalization of graphene-based nanoparticles on the local electrical properties of epoxy nanocomposites

In this study, we put forward a non-covalent π-π interaction between graphene nanoparticles (G) and pyrene-based molecule (py) to give the functionalized (G-py). The proposed modification has proven be winning solution aimed at safeguarding graphene's striking electronic properties, while favoring more effective nanofiller dispersion due decrease in viscosity with consequent improvement of rheological properties formulated nanocomposites. Tunneling Atomic Force Microscopy (TUNA) analysis was carried out using G-py weight percentages both below above Electrical Percolation Threshold (EPT) investigate electrical behavior conductive nanodomains epoxy/graphene systems. results are perfect agreement ones. greatly enhances thermal stability graphene-based nanoparticles, also causing an increase oxidative thermostability
