Glycosaminoglycans as polyelectrolytes
Advances in Colloid and Interface Science, 2010One of the barriers to understanding structure-property relations for glycosaminoglycans has been the lack of constructive interplay between the principles and methodologies of the life sciences (molecular biology, biochemistry and cell biology) and the physical sciences, particularly in the field of polyelectrolytes.

This perspective seeks to identify an area of soft materials research focused on the study of functional polyelectrolytes. These materials combine the useful properties intrinsic to polyelectrolyte chains, with added functionality provided by specific molecular (or polymeric) functional groups that are present in the polymer backbone or as a pendant ...

Diffusion of Polyelectrolytes in Polyelectrolyte Gels
Macromolecules, 2017We have studied diffusion of polyelectrolyte probe molecules in a similarly charged gel matrix. A variety of factors that affect the polymer diffusion inside the gel were explored such as the charge density and the cross-link density of the gel as well as the solvent quality and the salt concentration of the medium.

Macromolecules, 2005
Monolayers of polyelectrolyte complexes are generated at solid surfaces using covalently attached monolayers of weak polyelectrolyte molecules (“polyelectrolyte brushes”) exposed to aqueous solutions of oppositely charged polyelectrolytes. The adsorption of the charged polymers onto the brush-coated substrate is measured as a function of deposition ...

Scaling behaviour of polyelectrolytes and polyelectrolyte brushes
Il Nuovo Cimento D, 1994Simulation results as well as experimental data indicate that full stretching of flexible polyelectrolytes will not occur under experimentally realizable conditions. Using density-dependent swelling exponents ν(ϕ) as suggested by Stevens and Kremer from the results of a MD simulation study, we present an Alexander-de Gennes-like scaling picture for the

Enhanced Dewatering of Polyelectrolyte Nanocomposites by Hydrophobic Polyelectrolytes
Langmuir, 2012We demonstrate that increasing the hydrophobic environment around the charge center of a polyelectrolyte (PE) not only decreases the water content of an adsorbed PE layer but can even dewater up to ~50% of an initially hydrated substrate. The results of this work are expected to yield new stratagies to dewater PE systems and have potential applications

Polyelectrolyte brushes and polyelectrolyte adsorption layers
Berichte der Bunsengesellschaft für physikalische Chemie, 1996AbstractThe structure of brushes and adsorption layers of polyelectrolytes containing strong and weak groups is analysed, using both a numerical self‐consistent‐field (SCF) model and approximate analytical expressions. The latter are based upon a local electroneutrality approximation (brushes) or upon a mutual compensation of the adsorbed polymer ...

Polyelectrolyte Multilayers on Weak Polyelectrolyte Brushes
Macromolecular Rapid Communications, 2003AbstractThe interaction of surface‐attached weak polyelectrolyte brushes, grown directly from the surface of a solid substrate by surface‐initiated polymerization, with weak polyelectrolyte molecules in solution is studied. In addition, the formation of PEL multilayers onto such brush substrates is investigated. A strong template effect is observed and

The Effect of Polyelectrolyte Architecture on Polyelectrolyte Complexation
2023Polyelectrolyte complexes (PECs) form spontaneously upon mixing aqueous solutions of oppositely charged polymers, forming a polymer rich complex phase and polymer poor supernatant phase. PECs are promising material platforms for various industrial applications due to their biocompatibility, low surface tension and stimuli-responsiveness.
