“…Corrosion resistance can be further enhanced by the addition of a corrosion inhibitor, either organic or inorganic. Many researchers have focused on blending a polymer with inorganic nanoparticles, such as Al 2 O 3 , ZrO 2 , SiO 2 , TiO 2 , Fe 3 O 4 , CdS, and ZnO, among others [10][11][12][13][14][15][16][17][18][19]. The presence of these nanoparticles between the interstices of the fibers can increase the surface roughness and the air entrapment, improving the hydrophobic character of the coating and thus reducing the corrosion rate.…”

This paper reports the use of the electrospinning technique for the synthesis of nanocomposite micro/nanofibers by combining a polymeric precursor with hydrophobic behavior like polyvinyl chloride (PVC) with nanoparticles of a corrosion inhibitor like ZnO. These electrospun fibers were deposited on substrates of the aluminum alloy 6061T6 until forming a coating around 100 μm. The effect of varying the different electrospinning deposition parameters (mostly applied voltage and flow-rate) was exhaustively analyzed in order to optimize the coating properties. Several microscopy and analysis techniques have been employed, including optical microscopy (OM), field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), thermogravimetric analysis (TGA), and differential scanning calorimetry (DSC). Water contact angle (WCA) measurements have been carried out in order to corroborate the coating hydrophobicity. Finally, their corrosion behavior has been evaluated by electrochemical tests (Tafel curves and pitting potential measurements), showing a relevant improvement in the resultant corrosion resistance of the coated aluminum alloys.

“…However, the Al doped samples have E g values greater than 3.24 eV with maximum value of 3.54 eV for Al 12.30 ZnO sample. The increase in the E g for AZO films indicates an increase in free charge carriers within the films, as explained by the Burstein-Moss effect [33][34][35][36]. Moreover, the increase in the E g with the increasing Al concentration is due to the fact that Al ions tend to occupy ZnO lattice planes, which leads to an increase in the number of transport path of charge carriers into ZnO lattice as confirmed by electrical parameters below.…”

“…IZO thin films can be prepared by using the sol-gel method [8,9], which has several advantages, such as ability to control the chemical composition, low growth temperature, simplicity, safety, and low cost. The structural, optical, and electrical properties of sol-gel-derived IZO thin films are strongly affected by various substrates [10][11][12][13]. The substrate type is a very important factor because different flexible substrates have different characteristics, and it is important to choose one that is chemically and thermally stable, transparent, perfectly insulating, and lightweight.…”

ZnO buffer layers were deposited on mica substrates using a sol-gel spin coating method. Then, a thin film of metallic Zn was deposited onto the ZnO buffer layer/mica substrate using a thermal evaporator, and the deposited Zn thin films were then thermally oxidized in a furnace at 500 ℃ for 2 h in air. Finally, In-doped ZnO (IZO) thin films with different In concentrations were grown on the oxidized ZnO film/ZnO buffer layer/mica substrates using the sol-gel spin-coating method. All the IZO films showed ZnO peaks with similar intensities. The full width at half maximum values of the ZnO (002) peak for the IZO thin films decreased with an increase in the In concentration to 1 at%, because the crystallinity of the films was enhanced. However, a further increase in the In concentration caused the crystal quality to degrade. This might be attributed to the fact that the higher In doping resulted in an increase in the number of ionized impurities. The Urbach energy (EU) values of the IZO thin film decreased with an increase in the In concentration to 1 at% because of the enhanced crystal quality of the films. The EU values for the IZO thin films increased with the In concentration from 1 at% to 3 at%, reflecting the broadening of localized band tail state near the conduction band edge of the films.
