Abstract
Abstract A one-step electrospinning technique was used to prepare a protective superhydrophobic PVDF-ZnO nanocomposite coating for aluminum against corrosion. The wettability and morphology of the prepared coating surfaces was characterized using water contact angle and contact angle hysteresis measurements, scanning electron microscopy, Fourier transform infrared spectroscopy and atomic force microscopy. In addition, the corrosion resistance for Al with {PVDF} polymer and the PVDF-ZnO nanocomposite coatings compared to the bare Al was investigated by electrochemical impedance spectroscopy and Tafel polarization techniques. The results showed that, the water contact angle and the contact angle hysteresis of the prepared PVDF-ZnO nanocomposite coating were 155
