Nanofibers with multifunctional properties hold great promise as they allow components for a wide range of medical applications. In this study, zinc oxide, silver nitrate and Polycaprolactone were used in the production of nanofiber composite material by coaxial electrospinning process. PCL concentrations of 5, 10, and 15% by weight were utilized in all of the samples, and different amounts of silver nitrate and zinc oxide were used. Functional groups of silver nitrate, zinc oxide, and Polycaprolactone materials were determined by Fourier transform infrared spectroscopy. Morphological analyzes were carried out with scanning electron microscopy. For all solutions, before coaxial electrospinning, physical properties such as density, liquid state ac conductivity, and viscosity were measured. For the 20 Hz–3 MHz frequency range, after coaxial electrospinning, D-factors and capacitance of nanofiber composite materials were measured and dielectric loss, permittivity, and the solid-state alternating current conductivity were calculated for all solutions. The effects of silver nitrate, zinc oxide, and Polycaprolactone concentration percentages on the solid-state ac conductivity and the dielectric constant were analyzed and comparisons were made with the results obtained.
