Long-term corrosion protection by a thin nano-composite coating

Super-Amphiphobic Coating System Incorporating Functionalized Nano-Al2O3 in Polyvinylidene Fluoride (PVDF) with Enhanced Corrosion Resistance

“…It is not possible to get a perfect fit from the scattered plot, therefore the values obtained on the first day were only estimates. The scattering of EIS data of the hydrophobic coating was also observed in other studies [18,27] and this is likely due to the presence of air bubbles on the coating/electrolyte interface due to the super-hydrophobic surface. During measurement, the bubbles could collapse and be diffused out of the system, causing agitation and system instability.…”

“…Lina Ejenstam et al [18] investigated the corrosion properties of hydrophobic multilayer nano-composite coating using a thin composite polyester acrylate (PEA)-TiO 2 -hexamethyl disiloxane (HMDSO) coating system. The study shows that it required all three layers to reach and maintain the desired corrosion protective property.…”

Liquid Flame Spray—A Hydrogen-Oxygen Flame Based Method for Nanoparticle Synthesis and Functional Nanocoatings

“…Also, hydrophobisation of the surface of wood materials is an important field (Moghaddam et al, 2013;Moghaddam et al, 2014), where direct nanoparticle deposition from the LFS has also been applied successfully (Moghaddam et al, 2015;Moghaddam et al, 2016). Superhydrophobic coatings can also be used to affect the corrosion properties of the surface (Ejenstam et al, 2013;Ejenstam et al, 2015a;Ejenstam et al, 2016), with a potential application field also for nanoparticle coatings (Ejenstam et al, 2015b). nanoparticle deposit on a paperboard (see e.g.…”

Fabrication and evaluation of Rb2Co(H2P2O7)2·2H2O/waterborne polyurethane nanocomposite coating for corrosion protection aspects

“…27 This improvement in the corrosion resistance of WBPU coating in the presence of DP nano-particles is attributed to; DP nanoparticles are well dispersed in WBPU coating, which restrict the diffusion of the corrosive ions and water through the WBPU coating lm. 28,29 Moreover, the large surface area and the small size of DP nano-particles, absorb more WBPU coating on its surface which reinforces the density of the WBPU coating lms, that way the transport paths for the corrosive ions and water to pass through the WBPU coating become longer and consequently inhibiting the corrosion process. 30 The effect of long time immersion of WBPU + 1.0% DP coating was shown in Fig.…”
