Examples of Dielectric Relaxation Spectra

There are many dielectric measurements of gels and numerous papers have been published [246-265]. The subjects vary widely from the sol-gel transition to the coulombic field of polyelectrolytes, some of which will be 

Rewriting this equation with the distance between the polymer ions, or the distance between the crosslink points L, the following equation also holds  

This equation is the same as the one for the entanglement of polyelectrolytes [259-261], which suggests that the relaxation mechanism is the same as the sodium acrylate gel. 

Several researches [259-261] also arrived at the conclusion regarding the morphology of gels that the magnitude of thermal fluctuation is almost the same size as the network. This high-frequency relaxation is regarded as a useful technique to study the motion of local counter ions, and future development of investigation in this field is expected. 

In this section, the information on the sol-gel transition of polysaccharide electrolyte gels obtained by dielectric relaxation spectra will be introduced
