Complexation of oppositely charged polyelectrolytes: effect of ion pair formation
Alexander Kudlay, Alexander V. Ermoshkin, Monica Olvera de la Cruz
Complexation in symmetric solutions of oppositely charged polyelectrolytes is studied theoretically. We include polyion crosslinking due to formation of thermoreversible ionic pair…

A Modified Random Phase Approximation of Polyelectrolyte Solutions
A. V. Ermoshkin, M. Olvera de la Cruz
We compute the phase diagram of salt-free polyelectrolyte solutions using a modified Debye-Huckel Approach. We introduce the chain connectivity via the Random Phase Approximation w…

Polyelectrolytes in the presence of multivalent ions: gelation versus segregation
A. V. Ermoshkin, M. Olvera de la Cruz
We analyze solutions of strongly charged chains bridged by linkers such as multivalent ions. The gelation induced by the strong short range electrostatic attractions is dramaticall…
