Heteropolysaccharides in sustainable corrosion inhibition: 4E (Energy, Economy, Ecology, and Effectivity) dimensions

Principles and theories of green chemistry for corrosion science and engineering: design and application

“…2,3 Fortunately, existing techniques can reduce the expense of corrosion by 15% (US $375 billion) to 35% (US $875 billion). 4,5 Before 1965, the efficiency of corrosion inhibitors was the primary factor in their selection, regardless of their effect on the environment. The first line of protection was utilizing inorganic species such as chromates, nitrates, nitrites, phosphates, molybdates, and tungstates because of their great potential at relatively low concentrations.…”

Cellulose, cellulose derivatives and cellulose composites in sustainable corrosion protection: challenges and opportunities

“…[29][30][31][32][33] A variety of carbohydrate polymer series, comprising both homo-and heteropolysaccharides like chitosan, starch, cellulose, chitin, gum Arabic, and others, are extensively employed in long-term corrosion prevention. [29][30][31][32][33][34] Carbohydrate polymers are highly soluble in aqueous electrolytes, unlike conventional polymers. Nevertheless, issues with their solubility, stability, and additional refinement of their inhibitive qualities may still need to be improved using carbohydrate polymers as corrosion inhibitors.…”

“…In their interactions with metallic surfaces, the majority of carbohydrates can act as adsorption centers due to the presence of polar functional groups such as -NH 2 , -OH, -CH 2 OH, -SO 3 H, -COO À , -NHCHCH 3 , -O-and -COCH 3 . [29][30][31][32][33][34] Owing to their polymeric nature and abundance of adsorption sites, carbohydrate polymers should bind to the metallic surface to form a highly potent, chelating and persistent complex. [29][30][31][32][33][34] Furthermore, the polar functional groups of electrolytes may undergo deprotonation or protonation based on their specific type.…”

[29][30][31][32][33][34] Furthermore, the polar functional groups of electrolytes may undergo deprotonation or protonation based on their specific type. Consequently, chemisorption and physisorption of carbohydrate polymers are possible on the surface of metals, with the physiochemisorption mechanism being the primary attachment mechanism.…”

“…Consequently, chemisorption and physisorption of carbohydrate polymers are possible on the surface of metals, with the physiochemisorption mechanism being the primary attachment mechanism. [29][30][31][32][33][34] The general requirements of a compound to be used as a corrosion inhibitor are schematically presented in Fig. 5.…”
