Polymeric nanocomposites coatings for the corrosion protection of steel

Abstract

Corrosion declared as the primary mechanism for the degradation of infrastructure, failure of metallic materials used in various industries such as pipelines in oil and gas industry, which results in huge economic loss, safety, and environmental problems. In this research, polymeric Nano composite smart coatings synthesized and evaluated for its performance. N-Methyl thiourea chosen as the core material to be encapsulated in Nano tubes using some experimental techniques. The mode of action of the novel smart coating involved two functional strategies. One is the polymeric matrix that offers physical barrier against corrosion. The other strategy involves the release of the loaded nano containers upon the formation of cracks. Once the release occurs, the methyl thiourea can act as corrosion inhibitor and as self- healing agent. Structural characterization was applied to the loaded nanotubes using SEM, XRD, FITR and TGA analyzer. While the performance evaluation of the smart coatings was conducted using gamry device via EIS test which showed the increase in corrosion resistance with time and confirmed the efficiency of the new nano composite smart coatings(NMTU) to perform corrosion inhibition and self-healing on the surface of steel substrate, protecting it from corrosion and so can be applied in various industries and to machine parts to improve their mechanical and anti-corrosive properties.future researches for the development of new loaded inhibitors nano containers of higher performance and more environmentally friendly is highly recommended.Also it is recommended to try these smart coatings in different applications in(Oil and gas, Automotive, Aerospace, Textile, Manufacturing, Electrical fields).
