Abstract

In this work, the electrospinning technique is used for the synthesis of
micro/nanofibers using a polymeric precursor with hydrophobic (even
superhydrophobic) behaviour such as polystyrene (PS) or polyvinyl chloride
(PVC). These electrospun fibers are deposited onto aluminum substrates
(6061T6). The effect of varying the different electrospinning deposition
parameters (mostly applied voltage and flow-rate) will be exhaustively analyzed
in order to optimize the resultant electrospun coatings. Several fiber
characterization tests have been performed, including Field Emission Scanning
Electron Microscopy (FE-SEM), Atomic Force Microscopy (AFM),
Thermogravimetric analysis (TGA),
Differential Scanning Calorimetry (DSC),
Optical Microscopy (OM) and Water
Contact Angle (WCA) measurements.
Furthermore, the anti-corrosion properties of these electrospun coatings can be
enhanced by the addition of metal oxide nanoparticles (ZnO) that act as corrosion inhibitors. Finally, electrochemical corrosion tests (Tafel and pitting tests) have
been performed, showing an improvement in the resultant corrosion resistance of the aluminum alloys coated by the combination of both polymeric films with
metal oxide inorganic nanoparticles.
