Polymer Thin Film Growth and Roughness (General, Advance)

Computer simulation models are used to study interface dynamics in driven (electrophoretic) deposition of polymer chains on an impenetrating substrate. Density profile, interface growth, and scaling of roughness with molecular weight, field, and temperature are examined in detail and empirical laws are identified where ever possible. Attempts are also made to study the film formation in a multi-component system with hydrophobic and polar components in evaporating aqueous solvent on an adsorbing substrate. Effects of water concentration on the interface width and phase-partitioning are examined.
