Slip and friction mechanisms at polymer semi-dilute solutions / solid interfaces
Marion Grzelka, Iurii Antoniuk, Eric Drockenmuller +3
The role of the polymer volume fraction, , on steady state slippage and interfacial friction is investigated for a semi-dilute polystyrene solutions in diethyl phthalate in cont…
Boundary flow of viscoelastic polyelectrolyte solutions
Chloé Barraud, Benjamin Cross, Cyril Picard +3
We report an investigation of the equilibrium and dynamic properties of polyelectrolyte solutions confined between platinum surfaces with a dynamic Surface Force Apparatus. The pol…
Wall slip of complex fluids: interfacial friction or slip length?
Benjamin Cross, Chloé Barraud, Cyril Picard +3
Using a dynamic Surface Force Apparatus, we demonstrate that the notion of slip length used to describe the boundary flow of simple liquids, is not appropriate for viscoelastic liq…
Friction of polymers: from PDMS melts to PDMS elastomers
Marceau Hénot, Eric Drockenmuller, Liliane Léger +1
The slip behavior of polydimethylsiloxane (PDMS) polymer melts flowing on non-adsorbing surfaces made of short non-entangled PDMS chains densely end-grafted to silica has been char…
