Polyelectrolyte - Wikipedia
网页Polyelectrolytes are polymers whose repeating units bear an electrolyte group. Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions (water), making the polymers charged.
Polyelectrolyte - an overview | ScienceDirect Topics
网页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.
A comprehensive review on polyelectrolyte complexes
网页2017年11月1日 · Ionized polyelectrolytes in solution can form complexes with oppositely charged polyelectrolytes, known as polyelectrolyte complexes (PEC). Polyelectrolyte complexes have a wide range of applications in biomedicine, nutraceuticals, cosmetics and pharmaceuticals.

网页2017年12月14日 · From the beginning of life with the information-containing polymers until the present era of a plethora of water-based materials in health care industry and biotechnology, polyelectrolytes are ubiquitous with a broad range of structural and functional properties.
Polyelectrolytes: Science and Application | SpringerLink
网页2014年1月1日 · Polyelectrolytes, which are a macromolecule dissolved in water or polar solvent, have gained a wide attention among scientists and engineers for their wide application areas.
Polyelectrolyte | chemical compound | Britannica
网页electrolyte, in chemistry and physics, substance that conducts electric current as a result of a dissociation into positively and negatively charged particles called ions, which migrate toward and ordinarily are discharged at the negative and positive terminals (cathode and anode) of an electric circuit, respectively.
Polyelectrolytes, Properties - SpringerLink
网页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.
Polyelectrolyte - an overview | ScienceDirect Topics
网页Polyelectrolytes are widely used to modify surfaces and to stabilize or destabilize colloidal dispersions. Applications can be found in food technology, mineralogy, paint production, and in a wide variety of other industrial processes.
网页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 …
