Recent Progress of Polymeric Corrosion Inhibitor: Structure and Application

Abstract

An anti-corrosion inhibitor is one of the most useful methods to prevent metal corrosion toward different media. In comparison with small molecular inhibitors, a polymeric inhibitor can integrate more adsorption groups and generate a synergetic effect, which has been widely used in industry and become a hot topic in academic research. Generally, both natural polymer-based inhibitors and synthetic polymeric inhibitors have been developed. Herein, we summarize the recent progress of polymeric inhibitors during the last decade, especially the structure design and application of synthetic polymeric inhibitor and related hybrid/composite.

Exploring the Efficacy of Polysaccharides as Green Corrosion Inhibitors: A Comprehensive Review

“…Starch as a Corrosion Inhibitor [ 90–92 ] : Film formation : Starch can form adhesive, protective films on metal surfaces due to its ability to adsorb onto the metal interface. These films act as a physical barrier, blocking the access of corrosive agents to the metal substrate. Passivation : Starch‐based inhibitors can facilitate the passivation of metals by promoting the formation of stable oxide layers.…”

New Inhibitor Based on Hydrolyzed Keratin Peptides for Stainless Steel Corrosion in Physiological Serum: An Electrochemical and Thermodynamic Study

“…Certain details for the corrosion current density calculation will be provided below. Equation (2) shows that the corrosion process rate is described by the two terms: the anodic and cathodic ones. This allows for the graphical determination of the main corrosion parameter, i corr , by plotting semilogarithmic polarization curves both for the anodic and for the cathodic processes, as shown in Figure 5.…”

“…The polymer inhibitor action mechanism consists of the physical, chemical or mixed adsorption (covering both features) of macromolecules possessing numerous active centers. These determine the polymer’s ability to interact with the metal surface, forming protective films and, thus, blocking the effects of metallic oxidation and corrosion processes, respectively [ 1 , 2 , 3 ].…”

Vapor-etching honeycomb-like zinc plating layer for constructing anti-corrosion lubricant-infused surfaces

“…Corrosion of metal materials is unavoidable in daily production and life; it causes significant wastage of resources and energy and even leads to potential safety issues ( Zhang et al, 2018 ; Wang and Cao, 2023 ; Wang et al, 2023 ). How to improve the corrosion resistance of metal materials is an important research topic in the field of engineering equipment, materials, and advanced manufacturing.…”
