阴离子型聚电解质盐溶液性质的研究进展

Development of the Study on Salt Solution Properties of Anion Polyelectrolyte

阴离子型聚电解质在极性溶剂中会发生电离,导致大分子链上带有大量的净负电荷。它在盐溶液中会与一些反离子,特别是多价金属阳离子等发生作用,从而使大分子形态发生改变,光学性质,电化学性质随之发生变化,作用强烈时,可发生沉淀。

Anionic polyelectrolytes can ionize in polar solvent, forming macromolecule chains with lots of anionic charge. These macromolecule chains could react with cation ions(such as metal ions) in salt solution.Consequently, the conformation of the macromolecule could change, and in the meantime its optical and electrochemical properies could be changed as well precipitation would occur if the reaction is strong enough.
