Abstract:
This article focuses on the designing and modification of MoS2 oxide nanosheets with graphene quantum dots and polyaniline. The main aim is to take the advantages of MoS2 oxide, graphene quantum dots, and polyaniline in enhancing the long-term performance (including corrosion) of exterior nanocomposites. For this purpose, the synthesized MoS2 was treated via a Sol-Gel process to enter graphene quantum dots. The modified hybrid nanosheets were characterized by Fourier transform infrared spectroscopy (FTIR) and Field Emission Scanning Electron Microscopy (FE-SEM). It was approved that the polyaniline has been successfully polymerized on the MoS2 oxide nanosheets in forms of non-covalent bonding through π-π interactions between a quinoid ring of PANI and covalent bonding through reaction with the epoxide group. The modified nanosheets were introduced into a typical epoxy matrix and then subjected to accelerated corrosion cycles. The results revealed a considerable improvement in corrosion resistance, which is provided with Electrochemical Impedance Spectroscopy (EIS).
