Abstract
Polymeric nanofibers are a promising technology to protect the metal surfaces from corrosion. Through the literature search, the use of polyacrylonitrile nanofibres (PANNFs) as a corrosion inhibitor coating for aluminum
alloys has not been evaluated. This work includes the development of a new, lightweight, high surface area and
efficient coating of PANNFs that produced using electrospinning process to resist the corrosion of aluminum
alloys (AA5083) which immersed in 0.6 M NaCl at alkaline medium (pH = 12) and acidic medium (pH = 1)
at a range of temperatures (293–323) K. The PANNFs coating was successfully deposited on AA 5083 specimens,
where these samples were considered as a collector electrode in the electrospinning process. The corrosion experiments of the aluminum alloys coated with PANNFs before and after immersion in both corrosive mediums were
investigated using cyclic potential polarization (CPP). The results confirmed that the PANNFs coating was able to
protect the surface of the aluminum specimens from corrosion, by reducing the corrosion current and increasing
the surface polarization resistance, thus reducing the corrosion rate. The protection efficiency was found in the
alkaline medium 98.8% while in the acidic medium 83.3%. So, it was in both mediums decreased with the increase
in temperature. The shape, distribution and size of the polymeric nanofibers that formed the coating were also
examined using field emission scanning electron microscopy (FE-SEM) and the percentages of the structural
components of these fibers were detected using the X-ray dispersion spectroscopy (EDS). The surface of aluminum specimens was completely covered by PANNFs. These electrospun nanofibers have worn out and lined up
spacing after immersion in the corrosive mediums. The diameters average of PANNFs was found to be about
200 and 150 nm before and after immersion, respectively.
