Dielectric spectroscopy by differential measurements in transmission lines on sodium dodecyl sulfate micelles in water
چکیده انگلیسی

A sodium dodecyl sulfate micellar solution in water was studied by Broad Band Dielectric Spectroscopy to investigate the relaxation processes. The experimental complex permittivity vs. frequency was analyzed by fitting the experimental data to three different models. The simplest one uses two Debye relaxation processes, one for bulk water and one for micelles contribution. The second model uses a Debye relaxation process for water and a Cole–Cole one for micelles, the third uses two Debye relaxation processes instead of the Cole–Cole one. Step amplitudes and relaxation time constants were obtained for the different processes. The sample Ohmic conductivity was also studied.
