(Elsevier, 2024) Gorguluer, Omer; Coskun, Ramazan; Yalcin, Orhan; Okutan, Mustafa; Uslu, Hasan; Doganay, B. Seyma
Acorn cupule extract doped different hydrogels were prepared to examine their structural morphological and dielectrical properties at room temperature. Structural, morphological and dielectrical parameters for all samples were found by using the XRD, SEM, EDX and impedance spectroscopy. The conductivity, capacitive effect and electronic circuit properties for acorn cupule extract doped hydrogels have not studied before in the literature. Therefore, the complex impedance, capacitance, phase angles, dielectric constant, tangent factor, electric modulus and frequency evolution of ionic conductivity (s -parameters) were successfully analyzed in detail using impedance spectroscopy in the frequency range of 10 2 to 10 7 rad/s at RT. Furthermore, the Cole -Cole plots of the dielectric constant adapted to the Smith chart and general RC equivalent circuit was showed in detail. It was determined that the dielectric effect was at its highest values in the frequency range of 10 2 to 10 5 rad/s.
