“…According to the weight loss experiments and electrochemical study, all these polymers were found to be effective inhibitors, which can achieve inhibitive efficiency as high as 95% at concentration as low as 10 mg/L. Moreover, our study also revealed the structure-property relationship for the design of new polymeric inhibitor, highlighting the important role of flexible linkage between the polymer main-chain and the charged group and the number of charged groups [69]. In addition to the above sulfur-containing polymeric inhibitors (Table 3), sulfur has also been introduced to resin coating.…”

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.

Developing highly efficient surfactant‐based corrosion inhibitor with multiple interaction sites toward metal surface is crucial for both industry and academy, which can advance the understanding of the anti‐corrosion mechanism and the structure‐activity relationship of inhibitor. However, achieving this goal remains a challenge because of the limited variety of ionic group and the structure of surfactant. Herein, a series of cobaltocenium‐based metallosurfactants is developed through click chemistry, where the cationic cobaltocenium is an ionic group and triazole is a potential coordination site with a metal surface. These metallosurfactants exhibit lower critic micelle concentration than corresponding quaternized ammonium with the same alkyl chains. Owing to the synergetic effect from coordination between triazole and metal surface as well as potential electrostatic interactions between cobaltocenium/protonated triazole with metal surface, these metallosurfactants exhibit highly efficient anti‐corrosion performance to mild steel with inhibitive efficiency as high as 95%. Moreover, such a synergetic effect enforces the hydrophilic group anchored to the metal surface and the tilted angle of the hydrophobic chain increases by increasing the chain length, which results unconventional acid‐resistant corrosion protection behavior.
