“…To address this issue, the dispersion method and surface modification of iNPs play crucial roles. Recent studies have shown that organic modification can be employed to enhance the dispersibility of iNPs in polymer matrices, including FEVE resin 2–4,17 . The utilization of nanosilica modified with (3‐aminopropyl)triethoxysilane or (3‐glycidyloxypropyl)trimethoxysilane has demonstrated successful dispersion of nanoparticles within the FEVE resin matrix.…”

[2][3][4]17 The utilization of nanosilica modified with (3-aminopropyl)triethoxysilane or (3-glycidyloxypropyl)trimethoxysilane has demonstrated successful dispersion of nanoparticles within the FEVE resin matrix. This regular dispersion has led to increased contact angles for both water and oil, ultimately improving the superhydrophobic properties of the nanocomposite coatings.…”

“…4 Furthermore, a combination of rGO and silica nanoparticles treated with KH-550 agents displayed uniform dispersion within the FEVE matrix, resulting in improved mechanical properties and anti-corrosion protection capabilities of the coating. 17 The inclusion of polyvinyl alcohol (PVA) modified silica (PVA-SiO 2 ) has shown positive effects on the properties of the polyvinylidene fluoride (PVDF) ultrafiltration (UF), for instance, the improvements in the mean pore size and porosity as well as reduction in the water contact angle of the membrane. In addition, the obtained UF membrane exhibited good anti-fouling property.…”

This study aims to investigate the effect of organically modified zirconium dioxide nanoparticles (m‐ZrO2 NPs) on the mechanical properties, morphology, and weather stability of fluoroethylene/vinyl ether copolymer (FEVE). To modify the surface of ZrO2 NPs, a 3‐(trimethoxysilyl)propyl methacrylate silane (TMSPM) organic coupling agent was utilized. The ZrO2 NPs were treated with 3 wt.% of TMSPM using a solution method with ultrasonication assistance at 50°C. Various amounts of m‐ZrO2 NPs (1, 2, and 4 wt.% of FEVE weight) were dispersed in a xylene solvent and mixed with FEVE resin. The mixture was then cured with polyisocyanate. The mechanical properties of the FEVE nanocomposite coatings, including impact resistance, adhesion, and abrasion resistance were measured. The morphology of the coatings was analyzed using scanning electron microscopy (SEM). To evaluate the weather stability of the coatings, an accelerated weathering test was conducted in a QUV/SPRAY chamber. This test could potentially affect the chemical structure, weight/thickness, and surface characteristics of the coatings. The carbonyl index, weight loss, and changes in mechanical properties of the coatings were monitored and discussed at different intervals during the accelerated weathering test. In addition, the morphology of the coatings after undergoing 42 cycles of accelerated weathering testing was analyzed. The results indicated that m‐ZrO2 NPs had a positive impact on the weather durability of FEVE resin, particularly in significantly enhancing the weather resistance of the FEVE‐based coatings. Therefore, these coatings exhibit potential for outdoor applications.Highlights Silane modified ZrO2 nanoparticles improve the mechanical properties of FEVE resin. The weather stability of FEVE resin increases as using modified ZrO2 nanoparticles. The suitable content of modified ZrO2 nanoparticles for FEVE resin is 2 wt.%. Mechanical properties of the nanocomposite reduce slightly after 42 cycle testing. Propose the mechanism for weather resistance of the nanocomposite coating.

“…The organic coatings based on fluoropolymer such as polytetrafluoroethylene (PTFE), tetrafluoroethylene/hexafluoropropylene copolymer, tetrafluoroethylene/perfluoro alkyl vinyl ether copolymer, fluoroethylene/vinyl ether copolymer (FEVE) have been used widely for outdoor applications because of their high weather resistance, good chemical resistance, high electrical insulation, good water and oil impermeability, high corrosion resistance, etc. [1][2][3][4][5][6] Among them, FEVE (commercial name of Lumiflon®) -a copolymer fluoropolymer that consisted of two monomers consisting of fluoroethylene (FE) and vinyl ether (VE) has been noted for possessing both characteristics of fluoropolymers and hydrocarbons. [7] Due to high chemical stability, the FE monomers could help polymer layer to resistant to UV rays and protect the unstable VE monomers the solubility of FEVE in the solvent, increase the gloss of paint film, and easily functionalize FEVE.…”

This paper presents the results of immersion assay on antifouling performance of a fluoropolymer nanocomposite coating on the steel substrate using natural seawater medium in laboratory. The fluoropolymer nanocomposite coating was composed in the presence of reinforcement additives, including organically modified titanium dioxide (m‐TiO2), organically modified zirconium dioxide nanoparticles (m‐ZrO2) and antifouling agent of Cu2O nanoparticles and fluoropolymer. The ratio of m‐TiO2/m‐ZrO2/Cu2O was fixed at 2/2/5 wt.% in comparison with the fluoropolymer weight. The immersion test was applied to evaluating the antifouling performance of the nanocomposite coating in the natural seawater and has been carried out in dynamic condition at the room temperature of 30 ± 0.1 oC during 60 days of testing. The change in characteristics of the nanocomposite coating was observed and recorded weekly including contact angle, color of coating and the released Cu ions content. Other characteristics such as infrared spectroscopy, surface morphology, abrasion resistance and adhesion of the nanocomposite coating were analyzed before and after testing. The obtained results showed that Cu ions could release with a low rate from the nanocomposite coating when rising immersion time and the release of Cu ions followed a linear equation. The contact angle and gloss of the coating were slightly reduced during testing period, indicating that the smoothness of the coating surface did not change significantly when immersed in natural seawater. The adhesion and abrasion resistance of the coating were almost unchanged after 60‐day testing. In summary, the nanocomposite coating has good antifouling performance when immersion under natural seawater in the laboratory, considering the above specific characteristics, including the synergistic effect of reinforcement fillers (m‐TiO2, m‐ZrO2 nanoparticles) and antifouling agent (Cu2O nanoparticles) in the polymer matrix. This in‐lab experiment in natural seawater medium has confirmed the nanocomposite coating's antifouling performance and facilitated practical deployment.

“…Moreover, the EIS technique application for evaluating coatings are well known for percolation assessment in different solutions. [16][17][18][19][20][21] However, it is hardly applied in assemblings where the coating is weakly adhered or even not adhered to the metallic surface, as is the case of flexible pipes.…”

Commercially, polyamide 12 (PA12) is one of the polymers applied as an internal insulation layer in offshore exploitation. The present study aims to produce a hybrid system based on PA12 with 5 wt% of a nanoclay grade (montmorillonite -MMT) and evaluate its effect on the barrier behavior of the PA12 matrix, the exact grade used in the pressure layer of flexible pipe, over carbon steel AISI 1020, metallic alloy responsible for providing the mechanical properties to flexible pipes. The barrier behavior, related to ion and molecule diffusion in synthetic production water, was assessed by Electrochemical Impedance Spectroscopy (EIS) and linear sweep voltammetry (LSV) analysis, which allow for interpreting the carbon steel corrosion mechanisms. One also carried out Fourier transform infrared, X-ray diffraction, and Scanning electron microscopy analyzes. The data showed that the MMT lamellae are well-dispersed in the PA12 matrix. EIS and LSV analysis results showed higher corrosion protection efficiency by the system composed of PA12/MMT once compared to the system without adding the load.
