Abstract:
This article focuses on the designing and modification of MoS2-oxide nanosheets using SiO2 nanoparticles and polyaniline. The main aim is to take the advantages of MoS2-oxide, SiO2, and polyaniline in enhancing the long-term performance (corrosion) of exterior nanocomposites. For this purpose, the MoS2-oxide was treated via a Sol-Gel process to enter SiO2. The modified hybrid nanosheets were characterized by Fourier transform infrared spectroscopy (FTIR), Thermogravimetric analysis (TGA), 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).
