This project involves correlation of novel computer simulations with experimental measurements of the nucleation and growth of surface polymer films. A key element is the incorporation of "chemical identity" into the simulations. Experimentally this will be mirrored by systematic structural variation of monomers, including functionalisation and branch sites. Growth laws, fractal dimension and morphology will be predicted from the simulations, and compared with experimental (microelectrode and electrochemical quartz crystal microbalance) data. A central theme is the relationship of simulation parameters to deliberate structural variations, with the long term aim of a predictive capability for materials design.
