“…1 The study of polymer degradation induced by UV radiation is well-documented within the literature. [3][4][5] Absorbing UV radiation brings about photo-oxidative degradation which in turn causes the breakdown of the hydrocarbon backbone of the polymer and produces free-radicals. As free-radicals are self-propagating, if the environmental conditions remain the same, they induce a rapid degradation of the coating system once the initial stage of free-radical formation is reached.…”

“…This property allows it to be widely used in energy-efficient window coatings, which can effectively reduce solar heat gain and reduce energy consumption. Balboni et al synthesized cerium dioxide thin films doped with vanadium pentoxide whose curves (Nyquist plots) maintain an inclination of about 45° and have excellent durability . In addition, it was shown that vanadium oxide-doped cerium dioxide and its resulting vacancy defects synergistically improve the electrochemical properties of manganese dioxide, which provides a new idea for the modification of manganese dioxide .…”

The “pinning effect” of VO2 was used to expose the (110) crystalline plane of WO3 monoclinic phase to explore the contribution of the high-energy crystalline plane to the electrochemical performance of the vanadium–tungsten (VW) complexes. The characterizations of the prepared sample were done by XRD, SEM, and EDS. The impedance value of VW2 (VO2/WO3) was improved by 8730 ohm·cm2 over epoxy resin, thereby showing the best anticorrosion effect. The reason for the enhanced corrosion inhibition of the VW material was that the highly active (110) crystalline plane gave higher activity to the oxygen defects, which was conducive to the formation of hydroxyl groups by adsorption of H2O and O2. At the same time, electrochemical cathodic reaction was inhibited. Second, the active hydroxyl group on the plane of the (110) high-energy crystal plane formed hydrogen bonds with epoxy resin, which not only improved the interaction between corrosion inhibitor and epoxy resin but also resulted in the emergence of intercalated lamellar insoluble hydroxide, which improved the shielding property of the coating. Third, the reduction protection brought by the V4+ ion led to the advancement of the corrosion resistance of the VW2 complexes. The present study completed the research system of tungsten oxide, which was of guidance for the control of the crystal plane and the design of anticorrosion pigments.
