“…16 Many siliconized epoxy hybrid materials were prepared using the above methodology and reported in literature. [17][18][19][20] However, reports on similar materials having urethane moieties are very rare. 21 The production of such novel hybrid sol-gel materials of superior mechanical and barrier properties is still a very challenging area for research.…”

Coating the surface of insulators used in a gas‐insulated switchgear (GIS) with nonlinear‐resistance material is expected to increase breakdown voltage by reducing the electric‐field concentration when metal particles adhere to the insulators. In this study, an epoxy resin with zinc oxide was used as a nonlinear‐resistance material. Tensile strength, adhesion by heat cycle test, hardness, and resistance to decomposition products of sulfur hexafluoride gas were evaluated for the nonlinear‐resistance material. It was confirmed that there were no problems with mechanical properties for application to GIS. The nonlinear‐resistance material was spray‐coated on actual post spacers, and the breakdown voltage was evaluated when metallic particles adhered to the post spacers. When the coating thickness was 20–35 μm, the breakdown voltage increased by about 8%. When the coating thickness was 50– 68 μm, however, the breakdown voltage increased by 23%, confirming that the breakdown voltage of an actual spacer improved. © 2023 Institute of Electrical Engineer of Japan and Wiley Periodicals LLC.

“…However, due to its high rigidity, low shock resistance, and hygroscopic properties, the use of epoxy resin as an anticorrosion coating has become questionable. The disadvantages can be compensated by using composites of different materials [ 15 ].…”

Eco-friendly inhibitors have attracted considerable interest due to the increasing environmental issues caused by the extensive use of hazardous corrosion inhibitors. In this paper, environmentally friendly PDG-g-PANI/Al2O3 composites were prepared by a low-cost inverse emulsion polymerization for corrosion inhibition of mild steel (MS) and stainless steel (SS). The PDG-g-PANI/Al2O3 composites were characterized by different techniques such as X-ray diffraction (XRD), UV/Vis, and FTIR spectroscopy. XRD measurements show that the PDG-g-PANI/Al2O3 composite is mostly amorphous and scanning electron micrographs (SEM) reveal a uniform distribution of Al2O3 on the surface of the PDG-g-PANI matrix. The composite was applied as a corrosion inhibitor on mild steel (MS) and stainless steel (SS), and its efficiency was investigated by potentiodynamic polarization measurement in a 3.5% NaCl and 1 M H2SO4 solution. Corrosion kinetic parameters obtained from Tafel evaluation show that the PDG-g-PANI/Al2O3 composites protect the surface of MS and SS with inhibition efficiencies of 92.3% and 51.9% in 3.5% NaCl solution, which is notably higher than those obtained with untreated epoxy resin (89.3% and 99.5%). In particular, the mixture of epoxy/PDG-g-PANI/Al2O3 shows the best performance with an inhibition efficiency up to 99.9% on MS and SS. An equivalent good inhibition efficiency was obtained for the composite for 1M H2SO4. Analysis of activation energy, formation enthalpy, and entropy values suggest that the epoxy/PDG-g-PANI/Al2O3 coating is thermodynamically favorable for corrosion protection of MS and exhibits long-lasting stability.
