Mathematical simulation of ultra-thin polymeric film spreading dynamics

The mathematical modeling of the dynamics for an ultra-thin perfluoropolyet her film spreading on a surface is described, including both endgroup and s urface effects. A system Hamiltonian, which includes nearest neighbor inter actions, surface, endgroup/endgroup, and endgroup/surface interactions, com bined with a kinetic Monte Carlo acceptance scheme controls the particle dy namics. Enhanced 3D visualization techniques address previous problems with particle evaporation and illustrate the validity of the model results. A f ractal analysis is also applied to the spreading front of the multilayer fi lm.
