Signatures of slip in dewetting polymer films
WebDense moratoriums of colloidal or grenular particles can display pronounced non-Newtonian behaviour, such as discontinued shear bulge and shear jamming. The essential contribution of particle plane crudeness furthermore cling forces confirms that stress-activated frictional communications can play a key role in these marvels. Here, by employing a system of …

WebMay 5, 2024 · Fluid films spreading on hydrophobic solid surfaces exhibit complicated dynamics that describe transitions leading the films to break up into droplets. For viscous fluids coating hydrophobic solids this process is called "dewetting". These dynamics can be represented by a lubrication model consisting of a fourth-order nonlinear degenerate … WebThin liquid polymer films on hydrophobic substrates are susceptable to rupture and formation of holes, which in turn initiate a complex dewetting process that eventually evolves into characteristic stationary droplet patterns. ...

WebSep 14, 2005 · We compare the flow behavior of liquid polymer films on silicon wafers coated with either octadecyl-(OTS) or dodecyltrichlorosilane (DTS). Our experiments show that dewetting on DTS is significantly faster than on OTS. We argue that this is tied to the difference in the solid/liquid friction. As the film dewets, the profile of the rim advancing … WebFeb 1, 2024 · It has been demonstrated that the dewetting of thin polymer films in air or under medium depends strongly on the long-range interaction, ...

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 … churchtown school term datesWebHowever, for RPS films, the polymer film stability switched from apparent slip dewetting to apparently stable.
