The synthesis of molecularly thin poly(p-styrenesulfonate) monolayers as an example for a negatively charged polyelectrolyte brush covalently attached to a planar solid surface is described. The polymer monolayers are generated directly at the surface of the substrate by using self-assembled monolayers of an azo initiator and radical chain polymerization of p-styrenesulfonate ethyl ester (ESS) monomer in situ. This grafting from approach yields surface-bound poly(p-styrenesulfonate ethyl ester) (PESS) molecules with high molecular weights and with high graft densities of the attached chains. The PESS monolayers can be transformed into a charged poly(p-styrenesulfonate) (PSS) monolayer through a polymer-analogous saponification reaction under mild conditions, and the reaction can be carried out to quantitative conversion. The thickness of the polyelectrolyte brush can be controlled from 2 to more than 35 nm in the dry, collapsed state.

The interaction of polystyrene sulfonate with coat proteins (CP) at neutral pH in different stoichiometric conditions and the formation of monodisperse nanoparticles were investigated. The nanoparticles were characterized using fast performance liquid chr
