“…The low values R po of C1 and C2 samples could be attributed to the presence of multiple microdefects caused by the lack of homogeneity in the bulk of these two coatings on prolonged immersion in the saline electrolyte at room temperature. This inhomogeneity allows free pathways for water and corrosive ions to emerge to the surface of the metal substrate . Reduced Rp values denotes deterioration of the coating integrity, and the trend in CPEdl values can be employed to support this assertion.…”

Hybrid organic-inorganic materials made from sol-gel precursors can be used as anticorrosion barriers on metal substrates. The modification of epoxy resins with silicones is an interesting approach toward the synthesis of hybrid materials that combine the advantages offered by epoxy resins with those of silicones. In this study, novel hybrid epoxy-silicon materials were synthesized using sol-gel chemistry and subsequently functionalized with 4,4 0 -methylenebis(phenyl isocyanate), incorporating urethane functionality into the final polymer. The study screened five different epoxide precursors for use in the synthesis of the new hybrid materials and optimizing their anticorrosion properties. Spectral characterization confirms the proposed chemical structures of the newly synthesized polymers. The newly developed polymers were painted on mild steel panels, thermally cured, and their thermal, surface morphological, adhesion, and anticorrosion properties were fully characterized. The new coatings were found to have excellent thermal stability and adherence properties to steel surface. The results of corrosion testing on coated steel panels following long-term immersion in a 3.5 wt % aqueous NaCl medium revealed that the polymer prepared using the epoxide precursor bisphenol A diglycidyl ether provided the best anticorrosion protection property among the synthesized polymers. This could be attributed to the excellent integrity and crosslink density properties in addition to the lack of microdefects in the surface of this coated sample as confirmed by scanning electron microscopy analyses. The newly prepared hybrid coatings reported in this study are very promising as an alternative to toxic chromate-based coatings.

“…The dielectric loss is a suitable parameter to determine the dielectric material in microelectronic device applications. While for this, with increasing the thickness of the film, dielectric loss gets decreases due to the elimination of space‐free charges, and these space charges lead to large‐frequency dispersion . Moreover, the dead layer of thin film originates from any of the following factors; (i) oxygen diffusion, (ii) modifications in the surface chemistry of electrode interfaces, and (iii) formation of a reactive layer at the electrode interface.…”

The effect of thickness on distorted double perovskite structured BiFe0.5Cr0.5O3 (BFCO) thin films have been investigated for the first time using soft chemical method over Pt(111)/Ti/SiO2/Si substrate. The X‐ray diffraction (XRD) shows the presence of both BFO and BCO phases and confirms the formation of double perovskite‐structured BFCO. The morphology of the films changes with the increase in layers signifying the thickness dependence. The magnetization (M) versus magnetizing field (H) curve was well consistent with magnetoresistance (M‐R) results and exhibits anisotropic magnetoresistance. Thickness‐dependent dielectric behaviors of BFCO thin films were deeply understood from space charge, intrinsic and extrinsic mechanisms. The BiFe0.5Cr0.5O3 crystal systems with 60 nm thin layer showed an improved magnetism and magnetoresistance properties and are applicable to future magnetic application in the field of spintronics as a promising device.
