WebJun 23, 2006 · Ultrathin polymer films on non-wettable substrates display dynamic features which have been attributed to either viscoelastic or slip effects. Here we show that in the weak- and strong-slip regime, effects of viscoelastic relaxation are either absent or essentially indistinguishable from slip effects. Strong slip modifies the fastest unstable … WebSep 6, 2007 · To characterize nontrivial boundary conditions of a liquid flowing past a solid, the slip length is commonly used as a measure.
