Polyelectrolyte complex
Polyelectrolytes are polymers whose repeating units bear an electrolyte group. ... Thus, recently, the biocompatible and biodegradable macroporous material composed of polyelectrolyte complex was described, where the material exhibited excellent proliferation of mammalian cells and muscle like soft … See more 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 See more The conformation of any polymer is affected by a number of factors: notably the polymer architecture and the solvent affinity. In the case of polyelectrolytes, charge also has an effect. Whereas an uncharged linear polymer chain is usually found in a random … See more Polyelectrolytes have many applications, mostly related to modifying flow and stability properties of aqueous solutions and gels. For instance, they can be used to destabilize a See more If polyelectrolyte chains are added to a system of charged macroions (i.e. an array of DNA molecules), an interesting phenomenon called the polyelectrolyte bridging might occur. The term bridging interactions is usually applied to the situation where a … See more Acids are classified as either weak or strong (and bases similarly may be either weak or strong). Similarly, polyelectrolytes can be divided into "weak" and "strong" types. A "strong" polyelectrolyte is one that dissociates completely in solution for most reasonable See more 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 … See more Polyelectrolytes have been used in the formation of new types of materials known as polyelectrolyte multilayers (PEMs). These thin … See more WebInspired by sequence-specific behaviors in biomolecular condensates, intracellular structures that assemble in part by electrostatic interactions, we study phase separation …
