Abstract

Molecular dynamics simulations based on a coarse-grained, bead-spring model are adopted to investigate the spreading of functional perfluoropolyether on a solid substrate. The spreading phenomenon has been described by the thickness profiles and molecule movements which evolve with time. The spreading mechanism has been analyzed in terms of both the driving term from the gradient of disjoining pressure and the resistance term from the bead-substrate friction and the film viscosity by dividing the spreading film into three regions.
