We give a short introduction into polyelectrolytes and show some of the problems of modeling charged polymer systems. We concentrate on two model systems. The first one consists of flexible polyelectrolytes exposed to a poor solvent. These polymers show interesting conformational behavior. We will discuss them and hint to the difficulties of observing conformational transitions in light scatter...

nano-films consisting of an alternating sequence of positively and negatively charged polyelectrolyteshave been prepared by means of the electrostatic layer-by-layer sequential assembly technique on mildsteels. the mild steels were pretreated electrochemically to modify the mild steel surface. the modificationof the mild steel surface resulted in increasing the adhesion of the obtained nano-fil...

A superoxide dismutase mimicking nanocomposite of remarkable functional and colloidal stability was developed by sequential adsorption polyelectrolytes metal complexes on nanoclay particles.

The escape problem of an active particle in orientationally steering potential fields is analytically solved. A trapping instability akin to the counterion condensation phenomenon polyelectrolytes theory found.

Cationic polyelectrolytes with pyridinium and 1,2-dimethylimidazolium functionalities based on a hyperbranched polyglycerol scaffold with a narrow polydispersity were prepared by a polymer analogous reaction in a one-pot synthesis. By the variation of the spacer lengths between the cationic functionalities and polyether scaffold, a simple method was developed to adjust the charge density and fl...

Aggregation of stiff polyelectrolytes in solution and angleand distance-dependent potential of mean force between two like-charged rods are studied in the presence of 3-valent salt using molecular dynamics simulations. In the bulk solution, formation of long-lived metastable structures with similarities to the raft-like structures of actin filaments is observed within a range of salt concentrat...

In mixtures of colloids and nonadsorbing polyelectrolytes, a Donnan potential arises across the region between surfaces that are depleted polyelectrolyte rest system. This tends to shift density profile towards colloidal surface leads local accumulation polyelectrolytes. We derive zero-field theory for disjoining pressure two parallel flat plates. Polyelectrolyte is allowed enter confined inter...

A novel method to prepare amphiphilic block polyelectrolytes with a strongly hydrophobic under homogeneous conditions is presented here.
