The Role of Nonlinear Friction in the Dewetting of Thin Film Polymers
Thomas Vilmin, Elie Raphael, Pascal Damman +4
The study of the dewetting of very thin polymer films has recently revealed many unexpected features (e.g. unusual rim morphologies and front velocities) which have been the focus…
Dewetting of Thin Viscoelastic Polymer Films on Slippery Substrates
Elie Raphael, Thomas Vilmin
Dewetting of thin polystyrene films deposited onto silicone wafers at temperatures close to the glass transition exhibits unusual dynamics and front morphologies. Here, we present…
Comb-like polymers inside nanoscale pores
Cyprien Gay, Elie Raphael
A new method of polymer characterization, based on permeation studies using nanoscale pores, was recently proposed by Brochard and de Gennes. In the present paper, we study how thi…
Hysteretic behavior of a polymer molecule immersed in an incompatible melt
Cyprien Gay, Elie Raphael
The radius of gyration of a polymer chain immersed in a low molecular weight solvent is known to vary monotonically with the solvent quality. Here, we consider the behavior of a ch…
