- What is the difference between cationic and anionic polyelectrolyte?
- The cationic polyelectrolyte shows an extended structure whereas the anionic polyelectrolyte exhibits a collapsed structure, and their structural differences decline with increasing the counterion size.
- Which cationic group ionizes in a polyelectrolyte solution?
- The typical cationic group in bio-polyelectrolytes is amine (−NH 3 +, e.g., in chitosan and in proteins). Aqueous polyelectrolyte solutions are electrically conductive, due to the presence of both the polyions and the counterions [ 24 ]. Strongly acidic groups (e.g., phosphate and sulfonate) ionize in solution over a very wide pH range.
- Which Polyelectrolytes have both cationic and anionic repeat groups?
- Polyelectrolytes that bear both cationic and anionic repeat groups are called polyampholytes. The competition between the acid-base equilibria of these groups leads to additional complications in their physical behavior. These polymers usually only dissolve when sufficient added salt screens the interactions between oppositely charged segments.
- Are polycations and polyanions electrically conductive?
- Polycations and polyanions are polyelectrolytes. These groups dissociate in aqueous solutions (water), making the polymers charged. Polyelectrolyte properties are thus similar to both electrolytes ( salts) and polymers (high molecular weight compounds) and are sometimes called polysalts. Like salts, their solutions are electrically conductive.
