Isothermal dielectric frequency scans

Thermomechanical, Dynamic Mechanical and Dielectric Methods Step-wise Isothermal Frequency Scans... 

Detailed examination of the relaxations requires isothermal scans of relative permittivity and dielectric loss factor as a function of frequency/ so that effective dipole movements and activation energies of relaxation times may be obtained. A typical pair of plots of d and e" values against log/is shown in Fig. 3.7. Graphs of dielectric data of this kind are sometimes called, rather... 

Dielectric Spectroscopy - Surface Characterization ofLiquid-borne Colloids When an oscillatory electric field is applied to a colloidal suspension, the electric double layer around the particle will be polarized. The complex dielectric properties of the suspension, the loss factor, and the relative permittivity are determined by performing several isothermal scans as a function of frequency in the range of 100-10 ° Hz. The dielectric relaxation of particles can be determined through the dielectric spectroscopy and the...
