Abstract in another language
The combination of two techniques (Small Angle X-ray Scattering and Atomic Force Microscopy) has allowed us to measure in reciprocal and real space the correlation length ξ of salt-free aqueous solutions of a highly charged hydrophobic polyelectrolyte as a function of the polymer concentration Cp, charge fraction f and chain length N. Contrary to the classical behaviour of hydrophilic polyelectrolytes in the strong-coupling limit, ξ is strongly dependent on −1/2 −1/3 f. In particular, a continuous transition has been observed from ξ ∼ Cp to ξ ∼ Cp when f decreased from 100 to 35. We interpret this unusual behaviour as the consequence of the two features characterising the hydrophobic polyelectrolytes: the pearl necklace conformation ofthechainsandtheanomalouslystrongreductionoftheeffectivechargefraction.
