Abstract

Nanocellulose (NC), a renewable and biodegradable nanomaterial derived from biomass, has gained attention for its potential in advanced anticorrosion coatings. Traditional anticorrosion methods like metallic coatings and organic corrosion inhibitors could provide protection. However, they often come with significant drawbacks, including toxicity and environmental issues. NC has its unique properties like high mechanical strength, large surface area, and biodegradability. This offers a promising alternative to these conventional methods. The review focuses on NC's roles as a reinforcement agent, hydrophobizing agent, and dispersion enhancer for various anticorrosive additives such as nanosheet fillers, corrosion inhibitors, and self-healing agents. Nevertheless, the adoption of NC-based coatings faces challenges, including limitations in long-term performance under real-world conditions and microbial environment. Furthermore, achieving cost-effectiveness for industrial-scale production remains a key challenge.
