Few-layer graphene/MoS2 composite coatings via jet cavitation processes for anti-corrosion applications
Source abstract
Abstract
In this study, few-layered MoS 2 (FL-MoS 2) and few-layered graphene (FL-FLG) were synthesized by an environmental-friendly jet cavitation process. This liquid exfoliation approach aimed to increase the aspect ratio and surface area of FL-MoS 2 and FLG, thereby enhancing their corrosion resistance performance in the polymer matrix of epoxy (EP). The electrochemical Tafel tests indicated that FL-MoS 2/EP showed a lower corrosion rate of 1.60 × 10 −5 mpy, which was significantly lower than the 1.94 × 10 −2 mpy of pristine substrate - cold rolled steel (CRS) by three magnitude. On the other hand, FL-MoS 2/EP showed significant corrosion resistance of 917 kΩ·cm 2, which was approximately 30,566 times higher than that of CRS. Via introducing FLG into FL-MoS 2/EP composite film, named FLG/FL-MoS 2/EP, the corrosion rate could be reduced from 1.60 × 10 −5 to 1.3 × 10 −5 mpy, resulted from the inhibit of FL-MoS 2 restacking in EP. These synergetic effects confirmed that FLG/FL-MoS 2/EP composite film was a promising candidate for anti-corrosion applications.
