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

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 ...

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.
