A Comprehensive Review on Polymer Coatings in Preventing Marine Corrosion
Abstract
Marine corrosion is a persistent challenge that threatens the durability of ships, offshore platforms, and submerged equipment, leading to significant economic and environmental consequences. Polymer coatings have become essential solutions, offering a powerful combination of mechanical strength, chemical resilience, and eco‐friendly properties. This review synthesizes cutting‐edge research to explore the advancements in polymer coatings designed to combat marine corrosion effectively. It aims to provide a clear understanding of innovative materials, including conductive polymers, nanocomposites, and sustainable binders, that enhance protection through mechanisms such as passive film formation, robust barrier properties, and antifouling capabilities. The significance of this study lies in its comprehensive overview of multifunctional coating technologies, such as epoxy, polyurethane, and silicone hybrids, as well as smart coatings with self‐healing and antifouling features. These innovations are critical for addressing the harsh challenges of saline environments, microbial growth, and mechanical wear. By consolidating the latest findings, this review serves as a valuable resource for engineers seeking durable coating solutions to extend the lifespan of critical assets. It also highlights emerging trends for researchers, including eco‐friendly additives, nanotechnology‐driven enhancements, and bio‐inspired surfaces that mimic natural protective mechanisms. This work is crucial for bridging the gap between fragmented research and practical applications. It offers insights into optimizing coating performance, mitigating environmental degradation in marine settings, reducing maintenance costs, and minimizing environmental impact. By guiding the development of sustainable, high‐performance marine coatings, this review offers a roadmap for innovative solutions that ensure long‐term protection and align with global sustainability goals.
