Reducing corrosion greatly diminishes corrosion related issues, which is approximately 3% of the worldwide GDP. The use of coatings that can withstand external stresses is one way to reduce the corrosion of oil and gas pipelines. Chitosan, which is a derivative of shrimp shells, can withstand chlorides from saltwater and is bacterialcidal, killing various microbes. Chitosan, as a large molecule, would not be able to directly bond to steel, so linker molecules must be used. Sulfuric acid or piranha is used to activate the steel surface, aminopropyltriethoxysilane (APTES) is bonded to the steel surface, with a linker molecule of glutaraldehyde, to bond chitosan. The research presented will detail the surface chemistry differences in APTES, glutaraldehyde, and chitosan bonding based on surface treatment, as well as the effect surface treatment has on chitosan coating adhesion. In addition, the effect of a corrosive environment on the two final coatings will be presented.
