With 3% of the worldwide GDP, or $2.2 trillion worldwide, spent on corrosion related issues, developing a coating method that can withstand external stresses would reduce the amount of money spent on repair, replacement, and clean-up. This research utilizes chitosan bonded to steel using silanes to prevent external corrosion of steel oil and gas pipelines. Because chitosan comes from shrimp, which live in a saltwater environment, the chitosan coating should be resistant to the saltwater environment, as well as microbial degradation. Aminopropyltriethoxysilane (APTES) is typically deposited using toluene as the solvent, although toluene poses health and safety issues to both humans and the environment. The research presented will examine the surface chemistry that arises as toluene is exchanged with biologically compatible solvents to deposit APTES, and the adhesion strength of chitosan bonded to sulfuric acid treated steel. The effectiveness of the chitosan coating in preventing corrosion will also be discussed.
