Chemically functionalized polymers as corrosion inhibitors: Effect of solubility, adsorption and coordination bonding

This article explores the role of chemically functionalized polymers as effective corrosion inhibitors, emphasizing the need for functionalization to enhance their protective properties. The study investigates the functionalization process that impacts polymer characteristics such as solubility, adsorption behavior, and coordination bonding, directly influencing corrosion protection efficiency. The study reviews covalent and non-covalent functionalized polymers, examining their corrosion inhibition mechanisms through interactions with metal surfaces. The potential of polymer-based composites, including metal/metal-oxide/polymer hybrids, graphene/polymer composites, and cluster-based coordination polymers (CCPs), for corrosion control is explored. The literature survey highlights the significant advancements in these areas, mainly focusing on self-healing capabilities and sustainable materials. Moreover, MXene-polymer composites are proposed as promising candidates for efficient corrosion inhibition. The paper also discusses the challenges associated with using polymer nanocomposites in corrosion inhibition and suggests strategies to overcome these challenges, advancing the development of more effective, environmentally friendly solutions.
