Fabrication of h-MoO3 Nanorods and the Properties of the MoO3/WEP Composite Coatings Research

Abstract

In this study, we prepared a novel coating composed of hexagonal molybdenum oxide (h-MoO3) nanofiller and waterborne epoxy resin (WEP) to provide corrosion protection. We optimized the h-MoO3 nanorod synthesis methodology first by changing different parameters (pH, temperature, etc.). Furthermore, the as-prepared h-MoO3 rods were characterized using a scanning electron microscope (SEM) and X-ray diffraction (XRD). Finally, the electrochemical impedance spectroscopy (EIS) test results verified that the anticorrosive performance of the composite coatings was improved by incorporation of low content of MoO3 nanofiller (0.5 wt.%) compared to pure WEP sample. This developed composite will provide a new insight for the design and fabrication of one-dimensional (1D) nanomaterial (e.g., nanorod) reinforced epoxy coating and other polymeric coating processes.

An In Situ‐Fabricated All‐Inorganic Perovskite/MoO3 Heterojunction by Chemical Vapor Deposition and Its Photoresponse Properties

“…The crystal orientations of MoO 3 are (022), (513), (800), and (424), corresponding to orthorhombic crystal α‐MoO 3 . [ 27 ] Figure 1e shows XRD patterns of the CsPbBr 3 /MoO 3 heterojunctions on SiO 2 /Si substrates. It can be observed that the diffraction peaks of both CsPbBr 3 perovskite and MoO 3 are reflected.…”

State of the art review on mechanical properties of sandwich composite structures

“…Shokri‐Oojghaz et al [ 107 ] characterized the effects of relative volume of CNT, aggregation, CNT distribution, geometry and loading on the mechanical properties of the nanocomposite sandwich cylinders and found that, in order to improve the mechanical properties of composites, it is beneficial to improve distribution of CNT compared to adding CNT content in the nanocomposites. Zhou et al [ 108 ] developed a theoretical model to study flexural properties of functionally graded nanocomposites. Further, they proved that width‐to‐thickness ratio, plate's aspect ratio and, relative volume and distribution pattern of CNTs significantly affects nonlinear flexural properties of composite structures.…”
