WebPolyelectrolyte complex formation and dye filtration. Solid polyelectrolyte complexes were formed by mixing 300 μL of 66+/−2 mg/mL aqueous anionic copolymer solutions and 220 μL of 15.0+/−1.5 mg/mL aqueous cationic copolymer solution in 10 mL water, and then adding 20 μL of a 50 mg/mL magnesium sulfate solution.
WebBoth natural and synthetic polyelectrolytes form strong complexes with a variety of proteins. One peculiar phenomenon is that association can take place even when the protein and the polyelectrolyte carry the same charge. This has been interpreted as if the ion−dipole interaction can overcome the repulsive ion−ion interaction. the paw pantryPolyelectrolytes 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.
