Biopolymers nanocomposite for material protection: Enhancement of corrosion protection using waterborne polyurethane nanocomposite coatings

Functionalizing graphene with titanate coupling agents as reinforcement for one-component waterborne poly(urethane-acrylate) anticorrosion coatings

“…In general, the impedance modulus |Z| at the lowest frequency in Bode impedance plots ( Figure 9A, B) can be used as a semi-quantitative indicator of corrosion resistance. The impedance modulus of WPUA coating was only 1.12×10 5 Ω.cm 2 , and increased to 6.93×10 6 Ω.cm 2 with the incorporation of only 0.7% T2-RGO.…”

“…Incorporating nanofillers into polyurethane coatings has been demonstrated as an effective approach to improve the corrosion resistance of organic coatings via increasing the electrolyte pathway length [5][6][7][8][9][10][11]. Graphene, which comprises a single-atom-thick crystal of sp 2 -bonded carbon, is regarded as a promising candidate for anti-corrosive nanofiller and has been largely reported and used for metal anticorrosion [12][13][14].…”

Glycerin-Grafted Starch as Corrosion Inhibitor of C-Mn Steel in 1 M HCl solution

“…In the last decade, many research works were focused on the use of "green" corrosion inhibitors, lacking in the adverse health issues connected to the organic compounds used in the past [8,9]. The use of biomaterials as corrosion inhibitors takes considerable attention due to their inherent stability, availability, cost effectiveness, and environmentally-friendly nature [10,11].…”

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

“…8 In this status, the incorporation of nanoparticles in organic coatings is a favorable approach for enhancing corrosion resistance of polyurethane coatings. 9,10 The improvement of the corrosion resistance and mechanical properties of organic coating using inorganic materials is a promising approach for coating system. [11][12][13] Recent works showed that inorganic materials improves the corrosion resistance of organic coatings by enlarging the route of corrosive ions and water in the coating to reach the metal/ coating interface and enhance the barrier effects of coating matrix.…”
