We experimentally confirm a longstanding theoretical prediction of counterion-induced polyelec-trolyte collapse in low dielectric media. The scattering behaviour of polystyrene sulfonate in different solvents with dielectric permittivities in the range of ϵ ≃ 12 − 180 is investigated. For high and intermediate ϵ media, typical polyelectrolyte behav...
Understanding the influence of counterion and backbone solvation on the conformational and thermodynamic properties of polyelectrolytes in solution is one of the main open challenges in polyelectrolyte science. To address this problem, we study the scattering from semidilute solutions of a semiflexible polyelectrolyte, carboxymethyl cellulose (CMC)...
We study the viscosity of polystyrenesulfonate with sodium and tetrabutylammonium counterions in aqueous and organic solvent media. We find that at low concentrations the Fuoss law (ηsp ∼ c1/2) is approximately obeyed, but at higher concentrations, an exponential dependence on the polymer volume fraction sets in. These findings are discussed in ter...

We study the conformational and flow properties of sodium polystyrenesulfonate in aqueous NaCl solutions in the high polymer, high added-salt region using rheology and small angle neutron scattering (SANS). For low salt concentrations, the
specific viscosity decreases with added salt as expected. At very high salt, however, the specific viscosity i...

We investigate the phase behaviour and scattering properties of a polymerised ionic liquid (poly(1-butyl-3-vinylimidazolium bis(trifluoromethanesulfonyl)imide)) in 24 solvents of varying dielectric constants and solubility parameters. The polymer is found to be soluble in polar aprotic solvents and insoluble in non-polar or highly protic solvents....
We studied the viscosity of semidilute aqueous solutions of sodium polystyrenesulfonate as a function of polymer and salt concentrations. The viscosity data were quantified by applying a scaling relationship between solution correlation length ξ = lgν/B and number of monomers g per correlation volume for chains with monomer projection length l. The...
