Polyelectrolyte - an overview | ScienceDirect Topics
A polyelectrolyte is a macromolecule that can dissociate to give polymeric ions when dissolved in water or other ionizing solvents. Because of the repulsion between charges on the polymer chain, the system expands when it is ionized in a suitable solvent.

Polyelectrolytes: Science and Application | SpringerLink
2014年1月1日 · Polyelectrolytes (PEs) are generally defined as macromolecules, which when dissolved in water, dissociate to give highly charged polymeric molecules [1 – 3]. As another definition, polyelectrolytes are polymers carrying either positively or …
Polyelectrolytes, Properties - SpringerLink
2014年1月1日 · Polyelectrolytes are polymers with ionizable groups [1 – 9]. In polar solvents, such as water, these groups ionize by either dissociation (e.g., carboxyl: −COOH<=>−COO − +H +), or proton-association (e.g., amine: −NH 2 +H + <=>−NH 3+), which also produces counterions in the surrounding solution.
