Sustainable Design and Production of Nano-Hybrid Smart Coatings

Corrosion problems in the processing industry are one of the critical problems worldwide. Many technologies/approaches are currently adapted to overcome corrosion problems, such as using organic corrosion inhibitors, green inhibitors, and coatings. Coating technology earned enormously advantages among these methods due to their applicability and long-term services. Due to these advancements in coating technology, corrosion costs have already minimized by billions. In recent times smart coatings have been developed with nanomaterials and nano-composites for the anticorrosion applications and found adequate protection against various types of corrosion. The primary concern associated with this coating technology is toxicity towards the environment and health. Several novel technologies and materials have been investigated to provide ecologically acceptable, sustainable, and effective anticorrosion coatings. Polymers made from renewable resources, such as soybean oil, castor oil, and other plant-based components are utilized for the formulations of coatings. Waterborne coatings employ water as a solvent rather than standard organic solvents, which reduces volatile organic compounds emissions. Graphene is a single layer of closely packed carbon atoms in a two-dimensional honeycomb structure, offers outstanding barrier characteristics and mechanical strength. The addition of graphene to polymer coatings improves their anticorrosion capabilities. Microcapsules carrying corrosion inhibitors or polymerizable monomers are used in smart coatings with self-healing characteristics. When the coating is broken, these capsules burst, releasing healing chemicals that rebuild the coating. This method extends the life of the coating, decreasing the need for frequent reapplications and eliminating waste. Polymer based nano-composite coatings can improve the mechanical, barrier, and anticorrosion qualities. which increase coating performance and minimising environmental impact
