摘要

The growing demand for eco-friendly, high-performance coatings has driven advances in sustainable coating technologies. This review critically examines recent developments in biopolymer-based and nanocomposite-enhanced coatings aimed at improving corrosion resistance, mechanical strength, and antibiofouling performance. Unlike traditional petroleum-based coatings with toxic additives, sustainable coatings employ renewable resources, green synthesis methods, and multifunctional designs to achieve high performance with minimal environmental impact. The review highlights key concepts in sustainable coating design, including bio-based materials and fabrication techniques such as sol-gel processing, electrospinning, and layer-by-layer assembly. Mechanisms for corrosion protection, enhancement of mechanical properties, and antibiofouling strategies are discussed, emphasizing the role of nanomaterials and naturally derived biocidal agents. Emerging trends in multifunctional and stimuli-responsive coatings are also reviewed. Selected case studies illustrate current achievements, challenges, and future directions, underscoring the potential of sustainable coatings for greener, safer, and more resilient materials across diverse applications.
