Phase diagram for the adsorption of weak polyelectrolytes at a soft charged surface
Article Abstract:
The adsorption of polyelectrolytes at oppositely charged surfaces is experimentally studied. The polymer surface coverage, [Gamma], at equilibrium is measured by two reflectivity techniques, ellipsometry and polarization modulated infrared reflection absorption spectroscopy (PM-IRRAS), as a function of the surface charge density [sigma], and of the polymer ionization degree, [alpha].

Determination of charge and molecular weight of rigid-rod polyelectrolytes
Article Abstract:
The Higashi method is used for synthesizing rigid-rod poly(aramide) polyelectrolytes and its effective charge is determined by using Electrophoresis NME spectroscopy and diffusion NMR spectroscopy. The molecular weight of the polymer is found to be 14000 g/mol.
