Nucleated dewetting in supported ultra-thin liquid films with hydrodynamic slip

摘要: This study reveals the influence of surface energy and solid/liquid boundary condition on breakup mechanism dewetting ultra-thin polymer films. Using silane self-assembled monolayers, SiO$_2$ substrates are rendered hydrophobic provide a strong slip rather than no-slip condition. On undergoing these changes, thin-film morphology changes dramatically -- from spinodal to which is governed by nucleation growth. The experiments reveal dependence hole density film thickness temperature. combination lowered hydrodynamic brings studied system closer conditions encountered in bursting unsupported As for films, critical nucleus size inferred free model. supported observed using high speed \emph{in situ} atomic force microscopy.
