Corrosion is a costly phenomenon that is largely responsible for the deterioration of various infrastructures. While there are many corrosion prevention techniques, polymeric coatings are the most cost-effective and frequently used methods for protection of metal surfaces. The most commonly employed polymeric coatings are non-renewable BPA-based epoxide resins. Common curing agents are also the derivatives of hazardous amines such as ethylene di-amine and methylene dianiline. Therefore, there is a growing demand to develop renewable and less-harmful precursors from biomass to replace rapidly depleting petrochemicals. This thesis focuses on the characterization and optimization of anti-corrosive polymeric coating formulations derived from renewable building blocks. Cardanol and vanillyl alcohol were used for epoxy synthesis and furfurylamine as the main precursor for amine synthesis. A polymer blends study was carried out to compare bio-based epoxy-amine systems to petroleum-based systems. Cardanol contains a rigid phenolic ring and a flexible C15 alkyl side chain, giving the material unique properties suitable for flexible polymer synthesis. The highly bio-based epoxy-amine systems exhibited the optimum coatings performance with an improvement in hydrophobicity, flexibility, impact resistance, and adhesion to the substrate, which contributed to an overall improvement in anti-corrosive properties.
