Investigation of the dielectric properties of acorn nest extract loaded hydrogels

In this study, acorn nest extract-loaded (ANH) hydrogels with different chemical contents were prepared by polymerization technique. Characterization, qualitative and morphological properties of the samples were performed by x-ray diffraction (XRD) technique, x-ray (EDX) EDAX and Scanning electron Microscope (SEM), respectively. Electrical and dielectric properties of the samples were measured by impedance spectroscopy at room temperature and in the frequency range of 102 rad/s to 107 rad/s. The dielectric properties for all samples were examined according to frequency and their physical causes were discussed in detail. Interface interactions and dipolar polarization mechanism for all samples were effective in the high frequency region, while electrode polarization was effective on dielectric and conductivity properties in the low frequency region. Cole-Cole plots and equivalent impedance circuits adapted to Smith chart for acorn cupule extract loaded hydrogels were shown with dielectric plane plots in detail.
