The Interactions of Polyelectrolyte Complex System in Solution

Polyelectrolyte materials exhibit unique properties and important applications in industry,due to their having the characteristic structure of polymer chain and electrolyte.However,polyelectrolyte would inevitably interact with other substances during their applications,which has remarkable influences on the properties of polyelectrolyte materials.This paper introduced the progress in studies on the interactions between polyelectrolyte and salt,surfactant or opposite charged polyelectrolyte in solution.Moreover,the influences of several factors,such as polyelectrolyte structure,charge density,hydrophobic property and concentration,on the interaction in polyelectrolyte complex systems were discussed.
