The emergence of nanotechnology has enabled the development of novel corrosion inhibition methods. Nanoparticles are highly effective inhibitors due to physicochemical properties like large surface area and tunable size/shape. They form protective surface films through adsorption and barrier mechanisms to separate metal substrates from corrosive environments. Their incorporation as additives into polymeric coatings enhances properties like UV resistance and self-healing. Understanding adsorption and interaction with corrosive species is key to leveraging inhibition mechanisms. Tailoring nanomaterial composition facilitates customized protection solutions. Sustainable nanoparticle-based formulations can replace toxic alternatives, promoting eco-friendly corrosion management for prolonged critical infrastructure functioning.
