Titre : Improved corrosion protection performance of electrophoretic epoxy coatings with the incorporation of amino-functionalized graphene oxide Type de document : texte imprimé Auteurs : Rui Gou, Auteur ; Shihong Zhang, Auteur ; Yi He, Auteur ; Changhua Li, Auteur ; Hongjie Li, Auteur ; Dan Sun, Auteur ; Guiyang Wu, Auteur ; Xi Yuan, Auteur ; Wen Chen, Auteur ; Jing Yan, Auteur Année de publication : 2024 Article en page(s) : p. 761-771 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Acier L'acier est un alliage métallique utilisé dans les domaines de la construction métallique et de la construction mécanique.
L'acier est constitué d'au moins deux éléments, le fer, très majoritaire, et le carbone, dans des proportions comprises entre 0,02 % et 2 % en masse1.
C'est essentiellement la teneur en carbone qui confère à l'alliage les propriétés du métal qu'on appelle "acier". Il existe d’autres métaux à base de fer qui ne sont pas des aciers comme les fontes et les ferronickels par exemple.

The PEI-GO/EP composite coating was successfully deposited on carbon steel through the cathodic electrophoretic deposition (C-EPD) process. The zeta potential, X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), transmission electron microscopy (TEM), atomic force microscopy (AFM), and thermogravimetric analysis (TGA) methods were used to characterize the GO and PEI-GO materials. The dispersibility of PEI-GO in epoxy electrophoretic paint was studied by TEM and the fracture surface morphology of the coatings was observed by scanning electron microscope (SEM). Electrochemical impedance spectroscopy (EIS) studies evaluated the corrosion resistance of composite coatings. In summary, the impedance modulus of PEI-GO/EP composite coating is two orders of magnitude higher than that of neat epoxy coating, with enhanced anticorrosion performance.

Revêtements protecteursIndex. décimale : 667.9 Revêtements et enduits Résumé : Applications of reduced graphene oxide (rGO) in epoxy (EP) anticorrosion coatings are hindered by its poor dispersibility and galvanic corrosion hazard with the metal matrix. With an excellent water dispersibility, the acid-treated g-C3N4 nanosheets (CNNS) can be physically combined with rGO through ultrasonic treatment so as to enhance the dispersion of rGO in waterborne epoxy. The structure and morphology of the new hybrids prepared by this simple ultrasonic treatment were characterized through FTIR, Raman, XRD, XPS, and TEM. The results show that the best anticorrosion performance of the coating is achieved in 0.5 M sulfuric acid when the mass ratio of CNNS and rGO in the hybrid is 1:5. Compared with the case of pure EP coating, the corrosion current density of the new hybrid decreases by one order of magnitude, and electrochemical impedance increases by nearly two orders of magnitude. The new CNNS@rGO hybrid prepared by a simple ultrasonic method has broad prospects in the field of waterborne epoxy resin anticorrosive coatings.

Stabilisants (chimie)Index. décimale : 668.4 Plastiques, vinyles Résumé : Insoluble sulfur (IS) is prepared at low temperature with graphene oxide (GO) as stabilizer and ammonium persulfate as initiator. The FTIR and Raman patterns show that the non-conjugate double bond of GO can couple to the long chain free radicals of IS. The TGA and EDS results show that the mass fraction of IS is 79.75 wt% in particles by refluxing method, much higher than that in particles by hydrothermal method, when the mass ratio in reactants of GO to sulfur was 3: 1. Under constant content of sulfur, the tensile stress and elongation at break of NBR/GO-S(h) and NBR/GO-S(r) composites are higher than those of NBR/Reduced GO composites with the addition of 3 phr GO-S(h), GO-S(r) and Reduced GO particles into NBR. It can provide a new technology for the preparation of IS with lower temperature, little energy consumption and less environmental pollution. It is also a new method for the modification and application of GO in rubber.

Revêtements organiquesIndex. décimale : 667.9 Revêtements et enduits Résumé : This study aims to prepare antibacterial coatings based on polyurethane and curcumin-modified graphene oxide. Curcumin-modified graphene oxide (GO-CU) as an antibacterial agent was prepared using the adsorption method. GO-CU was incorporated in polyurethane (PU) coatings at concentrations of 0.1 and 0.5 wt%. Synthesized GO-CU was characterized by Fourier transform infrared spectroscopy, UV–Vis spectroscopy, transmission scanning electron microscopy, and zeta potential measurement. Curcumin content in GO-CU was determined by thermogravimetric analysis. Antibacterial properties of GO-CU powder and PU coatings containing GO-CU were investigated by counting the colony-forming unit (CFU) of Escherichia coli (E. coli) strain. The results showed that curcumin was attached on GO-CU surface and curcumin content in GO-CU was about 32.9%. GO-CU provided a higher antibacterial effect against E. coli than GO. The antibacterial efficiency of PU coatings containing 0.1 wt% GO-CU was 85.8%; however, the increase in GO-CU concentration did not significantly increase the antibacterial efficiency of PU coating.

Surfaces (technologie)Index. décimale : 667.9 Revêtements et enduits Résumé : The coating with amphiphilic honeycomb surface containing modified graphene oxide was constructed by a three-step method for improved antifouling properties. Graphene oxide is modified with potassium hydroxide and γ-aminopropyltriethoxysilane, and then the product is dispersed in water and ethanol. Isophorone diisocyanate, polyethylene glycol, and γ-aminopropyltriethoxysilane are used to construct an amphiphilic prepolymer. The honeycomb surface is constructed during the evaporation of water and ethanol and the mixing of the modified graphene oxide and prepolymer. The amphiphilic honeycomb surface gives the coating fouling resistance and fouling release, while the modified graphene oxide gives the coating fouling degradation. The coating’s amphiphilicity, microstructure, and antifouling properties are characterized by the contact angle, confocal laser scanning microscope, scanning electron microscopy, benthic diatom, and bacterial adhesion. The results show that the coatings form an amphiphilic surface with a honeycomb microstructure and exhibit good antifouling properties. The water, diiodomethane, and 1-bromonaphthalene contact angle can be less than 20°. The size and depth of the honeycomb microstructure are about 600 nm and 100–200 nm. Compared with traditional polyurethane and waterborne silicone coatings, the resistance to benthic diatom and bacteria is increased by at least 28 and 400 times, respectively.
