摘要：
In this study, superhydrophobic films were prepared through a spraying process of carbon nanotube (CNT) suspension on aluminium alloy substrate and characterized by scanning electronic microscope (SEM) contact angles (CAs) and potentiodynamic polarization tests in 0.1 M NaCl solution. Results indicate the positive effect of superhydrophobic film on the CA (>160°) in comparison with the bare metal due to the high porosity density at the surface caused by the presence of CNTs. The electrochemical observations indicate the presence of a positive shift of Ecorr that confers a better corrosion resistance of the coated samples.
