Abstract  

Epoxy coatings with different mass fraction of carbon nanotube (CNT) is prepared with epoxy as matrix, amine silane as curing agent, fumed silica as disperse dispersant, and carbodiimide as modifying agent. The effect of CNT amount on properties of epoxy coating is overall evaluated by means of pull-off adhesion test, ball-on-disk ear test, electrochemical impedance spectroscopy (EIS) and filiform corrosion test. The results show that, the adhesion strength, abrasion resistance and corrosion resistance are improved remarkable for the epoxy coating with 2% (mass fraction) of CNT in comparison to that without CNT addition. All the above mentioned properties are further improved for the epoxy coating with 5% and 7% of CNT. Furthermore, when the epoxy coating with the addition of CNT is up to 10%, of which the adhesion strength and abrasion resistance decreased, while the corrosion resistance and conductivity reach the optimum.
Key words:  carbon nanotube      epoxy coating      adhesion      friction      corrosion      EIS
