A green and facile fabrication of rGO/FEVE nanocomposite coating for anti-corrosion application

A facile process was developed to fabricate rGO/fluoroethylene vinyl ether (FEVE) nanocomposite coating for anti-corrosion application. Dry rGO modified with PS sphere were prepared with good re-dispersibility and directly added into FEVE organic paint, forming a rGO/FEVE nanocomposite coating. Furthermore, the effect of modified rGO on structure and properties of composite coating was investigated in detail. It was found that the composite coating (1.5 wt%) displayed best mechanical properties (e.g. adhesion strength of 14 MPa) and anti-corrosive performance (e.g. corrosive current density of 7.6 × 10 −12 A/cm 2 ) comparing with other composite coating based on rGO. This work thus provides a facile and environmentally friendly method to prepare novel nanocomposite coatings with enhanced performance for various practical applications.
