Interplay of internal stresses, electric stresses and surface diffusion in polymer films
Fabien Closa, Falko Ziebert, Elie Raphael
We investigate two destabilization mechanisms for elastic polymer films and put them into a general framework: first, instabilities due to in-plane stress and second due to an exte…
Piercing an interface with a brush: collaborative stiffening
F. Chiodi, B. Roman, J. Bico
The hairs of a painting brush withdrawn from a wetting liquid self-assemble into clumps whose sizes rely on a balance between liquid surface tension and hairs bending rigidity. Her…
Self-assembly in solution of a reversible comb-shaped supramolecular polymer
Sandrine Pensec, Nicolas Nouvela, Audrey Guilleman +3
We report a single step synthesis of a polyisobutene with a bis-urea moiety in the middle of the chain. In low polarity solvents, this polymer self-assembles by hydrogen bonding to…
A Poisson-Boltzmann approach for a lipid membrane in an electric field
Falko Ziebert, David Lacoste
The behavior of a non-conductive quasi-planar lipid membrane in an electrolyte and in a static (DC) electric field is investigated theoretically in the nonlinear (Poisson-Boltzmann…
