摘要

The methods and strategies of analyzing dielectric spectra for typical polyelectrolyte solutions in the RF range are reviewed. Emphasis is placed on gaining insight into internal information about the studying system

including chain conformation

counter-ion distribution

phase transition

and the micro-structure of microgels and polymer networks.

Abstract

Polyelectrolyte solutions are more variable than uncharged macromolecule due to electrical interaction between charged molecules and surrounding counterions. Therefore

the subject of polyelectrolyte solutions has attracted a wide range of interests in both basic and applied research

and has also been extensively explored. However

the understanding of the molecular dynamics and conformation of polyelectrolytes in solution remains to be deepened

and universal consensus on some key issues have not been reached. Many methods have contributed to solving the above problems in different ways

including dielectric relaxation spectroscopy (DRS). In this perspective

we briefly reviewed the history of dielectric spectroscopic research on polyelectrolyte solution

with emphasis on summarizing our efforts. In particular

we expound the characteristics of DRS and its ability to obtain the internal information of the system of interest. Finally

we evaluate the advantages and limitations of the dielectric method and discussed future prospects of this field.
