NICOP - Development of computational methodologies to study marine fouling mechanism based on surface energetic attachment model
Abstract
Biofouling, in particularly of marine organisms to ship hulls, incurs the losses of the ship~s operation efficiency, fuel, maintenan""ce fee. Traditional paints containing tributyltin (TBT) and copper, though mitigate this problem, are restricted worldwide by 2008 d"ue to their toxicity. Environmentally friendly antifouling strategies are thus received much research efforts. The two recent direct"ions are non-toxic foul-release coatings and foul-resistant surfaces inspired by naturally occurring antifouling ones like porpoise,"" killer whale and shark skin. For the second direction, many researchers have proved that tailoring surface topography, energy, chem"istry or mechanics can help to decrease spores attachment density.To make antifouling surface design and fabrication more optimal a"nd less costly, it is very important to have a theoretical model that can predict cell attachment on different surfaces for a variet""y of marine species in specific environment. Three models have been proposed namely attachment point theory, the engineered roughnes""s index (ERI) model, and the surface energetic attachment (SEA) model.However, in the early stages of these models, several approxi""mations and simplifications have been made, which limit their predictable performance. In this research proposal, we propose further"" computational study to refine the SEA model by taking into account the important roles of surface energy, surface chemistry as well" as spore properties and behaviors.The aims of our project are to reconsider the SEA model by giving it a more rigorous statistical" mechanics treatment to gain a better understanding of the fouling phenomenon, and to improve the model for enhancing its predictive" capabilities.
