Polyelectrolyte gels in poor solvent: Equilibrium and non equilibrium elasticity
T. A. Vilgis, A. Johner, J. -F. Joanny
We study theoretically using scaling arguments the behavior of polyelectrolyte gels in poor solvents. Following the classical picture of Katchalsky, our approach is based on single…
Stretching necklaces
T. A. Vilgis, A. Johner, J. -F. Joanny
Polyelectrolytes in poor solvents show a necklace structure where collapsed polymer pearls are linked to stretched strings. In the present paper the elasticity of such chains is st…
Crosslinked polymer chains with excluded volume: A new class of branched polymers?
T. A. Vilgis
In this note microgels with and without excluded volume interactions are considered. Based on earlier exact computations on Gaussian mircogels, which are formed by self-crosslinkin…
Topological interactions in DNA catenanes
M. Otto, T. A. Vilgis
The elasticity of DNA catenanes, i.e. multiply linked DNA rings, is investigated using the Gauss invariant as a minimal model for topology conservation. An effective elastic free e…
