Electrolyte

electrolyteselectrolyticionic solution
Polyelectrolytes are polymers whose repeating units bear an electrolyte group.
Electrolyte solutions can also result from the dissolution of some biological (e.g., DNA, polypeptides) and synthetic polymers (e.g., polystyrene sulfonate), termed "polyelectrolytes", which contain charged functional groups.

Gel

Polyelectrolytes have many applications,mostly related to modifying flow and stability properties of aqueous solutions and gels.
See polyelectrolyte for more information.

They are used in water treatment and for oil recovery.

Polyelectrolyte adsorption

For more information on multilayer creation please see polyelectrolyte adsorption.
Adsorption of polyelectrolytes on solid substrates is a surface phenomenon where long-chained polymer molecules with charged groups (dubbed polyelectrolytes) bind to a surface that is charged in the opposite polarity.

Polymer

Polyelectrolytes are polymers whose repeating units bear an electrolyte group.
A polymer molecule containing ionizable subunits is known as a polyelectrolyte or ionomer.

Multi-parametric surface plasmon resonance

MP-SPR
The formation is measured using Multi-Parametric Surface Plasmon Resonance to determine adsorption kinetics, layer thickness and optical density.
In material sciences, MP-SPR is used for optimization of thin solid films from Ångströms to 100 nanometers (graphene, metals, oxides), soft materials up to microns (nanocellulose, polyelectrolyte) including nanoparticles.

PH

pH levelneutralpH value
A "strong" polyelectrolyte is one that dissociates completely in solution for most reasonable pH values.

Dissociation constant

K i binding affinityaffinity
A "weak" polyelectrolyte, by contrast, has a dissociation constant (pKa or pKb) in the range of ~2 to ~10, meaning that it will be partially dissociated at intermediate pH.

Ionic strength

Since the polyelectrolyte dissociation releases counter-ions, this necessarily affects the solution's ionic strength, and therefore the Debye length.
