MoS2-CNFs composites to enhance the anticorrosive and mechanical performance of epoxy coating

To enhance the anticorrosive and mechanical performances of carbon nanofibers (CNFs) in epoxy (EP) coatings, molybdenum disulfide (MoS 2 ) and γ- (2, 3-epoxypropoxy) propytrimethoxysilane (KH560) have been combined for inner reinforcement and outer surface modification based on CNFs . The electrochemical impedance spectroscopy, tensile testing and microhardness testing demonstrated that MoS 2 -CNFs (0.8%) composite can prominently enhance the anticorrosive and mechanical performance of the EP coating. Furthermore, the impedance of EP/MoS 2 -CNFs (0.8%) was higher than that of the pure EP and other composite coatings, and the Young’s modulus (EY) and tensile strength (σs) of EP/MoS 2 -CNFs (0.8%) were increased by 65.4% and 56.6%, respectively.
