We demonstrate in this paper the influence of solvent quality on the structure of the semi-dilute solution of a hydrophobic polyelectrolyte, partially sulfonated Poly-Styrene Sulfonate. Two solvents are used: (i) one mixture of water and an organic s

Publikováno v: Macromolecules / J Macromolecules 40 (2007) 6679-6691

The form factor of partially sulfonated polystyrene PSSNa (degree of sulfonation f =1, 0.72, 0.64 and 0.36), at polymer concentration 0.17M and 0.34M, without or with added salt (0 M, 0.34M, & 0.68M), is measured by Small Angle Neutron Scattering usi

Report

Adsorption of hydrophobic polyelectrolytes as studied by \emph{in situ} high energy X-Ray reflectivity

Autor: Baigl, Damien, Guedeau-Boudeville, Marie-Alice, Ober, Raymond, Rieutord, François, Sferrazza, Michele, Théodoly, Olivier, Waigh, Thomas A., Williams, Claudine E.

A series of well-defined hydrophilic and hydrophobic polyelectrolytes of various chain lengths $N$ and effective charge fractions $f_{eff}$ have been adsorbed onto oppositely charged solid surfaces immersed in aqueous solutions. \emph{In situ} high e
