摘要

Light scattering is a powerful technique for characterizing the elasticity

microstructures and dynamics of various functional hydrogels. The average bond binding energy and lifetime of the physical crosslinks in gel networks can also be extracted from dynamic light scattering characterization results.

Abstract

Functional gels exhibit unique properties that can be tuned by regulating their physical interactions and microstructures. However

quantifying the strength and fraction of these physical interactions and how they result in large-scale collective dynamical properties remains a significant challenge. From this perspective

we briefly review the theories and characterization method of light scattering on polyelectrolyte gels

with an emphasis on summarizing our efforts. In particular

we introduce our most recent work on an entirely new universality class of hierarchical gel dynamics for various types of physical gels

which is complementary to the light scattering studies on chemically crosslinked gels in the past five decades. By utilizing the hierarchical gel dynamics

we are able to extract the average bond binding energy of various physical bonds and the physical crosslinking density in the gels. Finally

we evaluated the advantages and limitations of the light scattering method and discussed the future perspectives in this field. It is anticipated that this perspective will facilitate the broad application of light scattering technique in the field of functional gels.
