“…ZnO nanoparticle is being used in a self-cleaning coating on a metal panel [45] and even in anti-corrosion nanocoating of carbon steel [46] in recent time. For its exquisite electric and optical properties, AZO has become the most promising candidate of transparent electrode for both photovoltaic [47] and plasmonic solar cell [48].…”

Al-doped ZnO (AZO) thin films are deposited on glass substrate by sol-gel spin coating using zinc acetate dihydrate as a precursor with different molar concentrations varying from 0.35 to 0.75 mol/L. To investigate the structural, electrical, optical and morphological properties of AZO films, XRD, four-point probes, HE measurement, UV-Vis spectrometry and SEM with EDX are used. Thickness of the thin film is measured by a surface profilometer. The structural characteristics show a hexagonal wurtzite structure with a (002)-preferred orientation. Optical study reveals that transmittance is very high (up to 90%) within the visible region and optical band gap, E g varies from 3.25 to 3.29 eV with Zn concentration. The carrier concentration increases and resistivity decreases with the increase in Zn concentration. Thin films fabricated with 0.75 mol/L of Zn concentration exhibit the best electrical property. SEM study shows non-uniform surface of the films where EDX confirms the formation of AZO. The results revealed by this study prompt a high interest to use AZO as transparent conductive oxide for advanced applications such as displays, solar cells and optoelectronic devices.

“…Among the NP family, ZnO gained a huge attention in making anticorrosive coating formulations due to its antimicrobial properties, high thermal stability, high electron mobility and high refractive index. 55,56 ZnOincorporated polysiloxane (PDMS) coating has been explored by Arukalam et al 57 They optimised the size and the concentration required for the highest anticorrosion performance. Surface morphology, liquid repellency and roughness of the coating were studied and performance was found to be a major function of size and PDMS:ZnO ratio.…”

Steel is known for its low cost of fabrication, high mechanical strength and hence is extensively used for drilling equipment, pipelines, ship building and offshore structures. Corrosion of steel is a costly problem in many applications especially in oilfield and marine environments which are known for the high temperature, high pressure and corrosive conditions. In this paper, nanocomposite coating is being explored as the preferred strategy to improve corrosion resistance for steel. Here, we will give details on the various coating materials, deposition techniques and the challenges involved in realising the most suitable coating on steel based on results of recent research. In addition, we also detail the filler specifications for getting high performance nanocomposites.

“…The corrosion inhibition is better in ZnO nanotetra-pods prepared using MWI due to its high purity, smaller size and higher tetrapod formation possibility when compared to hydrothermal and sol-gel methods. The smaller size range of the prepared ZnO makes it to have higher surface area, and more number of surface atoms, thereby inhibiting more corrosive activity [27].…”

Highly cross-linked zinc oxide (ZnO) with the nanorod morphology of tetra-pods was successfully prepared using a microwave irradiation (MWI) technique. In comparison with the available conventional techniques, the MWI technique has the advantage of producing different morphological structures with high purity and in a shorter reaction time. These tetra-pods consist of a ZnO core in the zinc blende from which four ZnO arms emerge in the wurtzite structure. In this investigation, the effects of irradiation times and the growth mechanism of ZnO nanotetra-pods were discussed. The structural, morphological and optical properties of ZnO nanorods were investigated by field emission scanning electron microscopy, X-ray diffraction, an ultra violet visible spectrometry and energy-dispersive spectroscopy. The electrochemical corrosion behaviours of an AZ91-grade Mg alloy and a ZnO/PN nanotetra-pod-coated Mg alloy were investigated. The Tafel plot revealed that the corrosion of Mg drastically decreased on coating with a thin layer of ZnO nanotetra-pods and PN (Mg/PN/ZnO) compared to Mg in a KOH electrolyte.
