Near surface concentration profile of sheared semi-dilute polymer solutions
Suzanne Lafon, Tiago Outerelo-Corvo, Marion Grzelka +5
Controlling the structure of polymer solutions near a solid surface is crucial for many industrial processes, as it significantly impacts solution flow and influences slip at the i…
Molecular rotors to probe the local viscosity of a polymer glass
Elham Mirzahossein, Marion Grzelka, Zhongcheng Pan +4
We investigate the local viscosity of a polymer glass around its glass transition temperature using environment-sensitive fluorescent molecular rotors embedded in the polymer matri…
Transition from viscoelastic to fracture-like peeling of pressure-sensitive adhesives
Marion Grzelka, Stefan Kooij, Sander Woutersen +2
We investigate the process of the slow unrolling of a roll of typical pressure-sensitive adhesive, Scotch tape, under its own weight. Probing the peeling velocities down to nm/s re…
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…
Viscoelasticity induced onset of slip at the wall for polymer fluids
Marion Grzelka, Iurii Antoniuk, Eric Drockenmuller +3
The progressive onset of slip at the wall, which corresponds to a slip length increasing with the solicitation time before reaching a plateau, has been investigated for model visco…
Temperature-Controlled Slip of Polymer Melts on Ideal Substrates
Marceau Hénot, Marion Grzelka, Jian Zhang +5
The temperature dependence of the hydrodynamic boundary condition between a PDMS melt and two different non-attractive surfaces made of either an OTS (octadecyltrichlorosilane) sel…
Capillary fracture of ultrasoft gels: heterogeneity and delayed nucleation
Marion Grzelka, Joshua B. Bostwick, Karen E. Daniels
A droplet of surfactant spreading on an ultrasoft ( Pa) gel substrate will produce capillary fractures at the gel surface; these fractures originate at the contact-…
