Corrosion related issues, including repairing, replacing, and clean-up, cost approximately 3% of the worldwide GDP, or $2.2 trillion annually. Developing a coating method that can withstand external stresses could prolong oil and gas pipelines, reducing costs. Chitosan, a derivative of shrimp shells, could be a useful coating, as it comes from a saltwater environment and is bacterialcidal. Aminopropyltriethoxysilane (APTES) bonded to steel serves as a linker between the steel surface and the chitosan coating. The research presented will examine the surface chemistry necessary to bond chitosan to piranha-treated steel, as well as the adhesion strength of the bonded chitosan. In order to determine the least amount of APTES necessary to obtain a strongly bound coating, five different percentages will be utilized. In addition, the effects of three corrosive environments on the chitosan coating, the silane bonds, and the underlying steel will be examined using the most strongly adhered APTES-chitosan coating.
