Synthesis of Mn-MOFs loaded zinc phosphate composite for water-based acrylic coatings with durable anticorrosion performance on mild steel

Abstract

The above scheme shows the preparation route of Mn-MOFs@Zn@acrylic coating. Mn-MOFs@Zn and water-based acrylic varnish were evenly dispersed in water; then the coating was applied to the surface of mild steel and then scratched with a knife.

Self-Oriented Functionalized MXene with Excellent Antioxidant Properties for Enhancing Anticorrosion Properties of Waterborne Epoxy Resin

“…As depicted in Figure , both the Nyquist and Bode plots of all specimens presented one time constant, thereby illustrating that the corrosion of steel in different solutions was mainly controlled by the charge transfer process of steel/solution interface . The capacitive arc radius observed in the Nyquist plots serves as a valuable index for evaluating the ease of charge transfer during corrosion reactions. , In Figure , the capacitive arc radii of steel immersed in solutions containing MPF are consistently larger than other samples, thereby indicating that MPF could effectively inhibit the corrosion reactions. Furthermore, as the concentration of MPF increased, its corresponding capacitive arc radius expanded, likely due to the increased adsorption of MPF onto the steel substrate.…”

Synthesis of ZnO Crystal with Micro‐Nano Structures by a Continuous Co‐Precipitation Method: Morphological Evolution and Mechanism Analysis

“…The concentration of Zn 2+ ions was measured three times following Chinese national standards (National Standard of the People's Republic of China, GB/T 10656-2008, Analysis of water used in boiler and cooling-determination of zinc-zincon spectrophotometry). [44,45] In this method, boric acid-potassium chloride-sodium hydroxide was prepared as a buffer solution, and zincon monosodium salt solution was adopted as a chromogenic reagent. In the 10 mL colorimetric tube, 2 mL of buffer solution, 1 mL of supernatant containing various zinc ion concentrations, and 1 mL of chromogenic reagent were added.…”

Water-Triggered Self-Healing Composite Coating: Fabrication and Anti-Corrosion Application

“…Among these approaches, incorporating healant-loaded containers into a coating for smart release control has drawn much attention because of its spontaneity and simplicity in the realization of self-healing under mild conditions. Various containers, including β-cyclodextrin [6,7], graphene oxide [8][9][10][11], silica [12][13][14], halloysite [8,15], titanium dioxide (TiO 2 ) [2], nanotubes porous polystyrene microspheres [3], metal-organic framework (MOF) [16,17], etc. have been used for encapsulation of corrosion inhibitors as well as the smart release of various corrosion inhibitors (benzotriazole [9,18], Ficus racemosa leaf extract [19,20], 8-hydroxyquinoline [21], cerium salt [22], molybdate [23] etc.).…”
