“…In an electrochemical investigation process, a three-electrode assembly cell having a mild steel working electrode of 10 cm² in surface area is utilized to demonstrate the metal in a consuming framework of 1 cm² unpolished area facing the solution as working electrode. A saturated calomel electrode with large rectangular platinum foil was used as reference electrode and counter electrode respectively at 35 o C temperature (9,10,16,38,40). Acetone, water, and a variety of emery papers were employed on the working electrode preparation.…”

“…It was found from the Langmuir adsorption isotherm that soluble polymers are efficient corrosion inhibitors as compared to the components like drugs, natural products, heterocyclic organic compounds, organic dyes, and so on, widely used as corrosion inhibitors, which covered the metal surface to repress the contact to the surface of metal and dampness (9,10).…”

As corrosion inhibitors for mild steel in acidic media, polymers are emerging materials due to its larger surface coverage area. This paper focuses on the characteristic of water-soluble solvent polyvinyl alcohol (PVA) at interface of mild steel under 0.5 M HCl, examined using electrochemical impedance spectroscopy, Tafel polarization, and weight reduction techniques. The findings of the study revealed that water-soluble polyvinyl alcohol as polymer inhibitor has restraint abilities, up to 93.7 percent for 3 hours in 0.5 M hydrochloric acid. An advanced form of high spatial resolution imaging of surface of mild steel at different stages was found by using scanning electron microscopy which shows that the sample immersed for 3 hrs in 0.5 M HCl with 100 ppm of water soulble PVA inhibitor provides good inhibition quality to corrosion on mild steel surface.

“…Naturally occurring substances of both plant and animal origin have been found to satisfy this need. Even though synthetic polymers [16][17][18][19][20] have been reported as corrosion inhibitors for metals in various corrosive medium, non-biodegradability is always a problem. In this regard bio-polymers offer distinct advantages as green corrosion inhibitors.…”

Maltodextrin (MLD) is introduced as a novel, potent green inhibitor for the corrosion control of zinc in 0.1 sulfamic acid. The corrosion and inhibition studies were done by electrochemical techniques such as potentiodynamic polarisation measurements and electrochemical impedance spectroscopy technique. Conditions were optimised to get maximum inhibition efficiency by varying the concentration of the inhibitor in the temperature range of 303–323 K. Activation and thermodynamic parameters were evaluated and discussed in detail. Suitable mechanism was proposed for corrosion and inhibition process. Surface characterisation was done by SEM, EDX and AFM techniques before and after the addition of inhibitor. The density functional theory calculations were performed and compared with experimental observations. Results indicated that inhibition efficiency increased with the temperature and inhibitor concentration. Maximum inhibition efficiency was found to be 62.3% for the addition of 0.4 g L−1 MLD. Theoretical calculations confirmed the experimental observations.
