A novel polymeric ionic liquid (PDBA-IL-NH2) using imidazolium liquids with short alkyl chains as monomers and two control (PDBA-IL-OH PIL-NH2) were synthesized. Their inhibition properties mechanisms explored via surface analysis, weight loss tests, electrochemical studies, adsorption isotherm analysis. The corrosion efficiency (CIE) of PDBA-IL-NH2 gradually increased increasing concentration, the largest was 94.67% at 100 ppm. At same concentration (50 ppm), abilities inhibitors in order > PDBA-IL-OH PIL-NH2 IL-NH2. Based on experimental investigation, synergistic effect electrostatic interaction, protonation, electron donor–acceptor interaction facilitated intensive entanglement coverage reticulated form metal, generated densest films protected metal from corrosive media. Ultimately, theoretical results molecular dynamics simulations quantum chemical study high agreement data, which confirmed proposed microscopic scale. This contributed valuable perspectives to design efficient ecofriendly inhibitors.

ACS Applied Nano Materials, Год журнала: 2024, Номер 7(11), С. 12249 - 12272

Опубликована: Май 31, 2024

Nanomaterials as additives are effective for improving the strength, toughness, corrosion resistance, and wear resistance of polymer coatings. The dimensionality nanomaterials (0D, 1D, 2D) has a significant influence on anticorrosion performance mechanism. It is also desired to develop composite using two or more (0D/1D, 1D/2D, 0D/2D) further enhance In this Review, categorized according their dimensionality. Their microscopic mechanism comprehensively summarized discussed. Then, synergistic effects additives, which consist nanomaterials, discussed in detail. Finally, current issues research prospects polymeric coatings
