Nano-Hierarchical Physio-Chemo Topographies to Develop Principles for Antifouling and Fouling Releasing
Abstract
There are four overaching aims in the execution of this research effort:Aim 1: Extend the thermodynamic model to predict antifouling as a function of surface topography to larger organisms and dimensions. This will include testing and optimize hierarchical topographies that have recently been fabricated for antibiofouling efficacy and non-wetting behavior and also characterization of wetting behavior of hydrophobic topographies in 3D with respect to pressure and time.Aim 2: Investigate the role of amphiphilicity on surface structure, material properties and antifouling efficacy of crosslinked networks. Develop a method of tailoring the surface energy of crosslinked networks to evaluate the effect on fouling properties. Investigate relationship between the antifouling performance and the corresponding surface structureAim 3: Investigate the effect of chemically grafted PDMSe with controllable hydrophilic/hydrophobic, charge balance, and polymer geometry on surface properties and AF/FR efficacy. Study the effect of hydrophilic/hydrophobic balance of polymer chains grafted to PDMSe. Study the effect of charge balance and chain geometry of polymer chains grafted to PDMSeAim 4: Test the validity of the Surface Energetics Attachment (SEA) model to predict antifouling efficacy of chemically grafted surface patterns. Study the effect of chemical nanoscale topography of grafted PDMSe surfaces on AF efficacy. Study the effect of chemical nanoscale pattern feature height of grafted PDMSe surfaces on AF efficacy
