Özet

Rosehip seed (RS) extract-loaded hydrogel samples RS1 (poly(AMPS-co-MBAAm), RS2 (poly(AMPS-co - CrA-co -MBAAm)), RS3 (poly(AMPS -co -MAA -co -MBAAm)) and RS4 (poly(AMPS-co -IA - co-MBAAm)) were prepared to examine their structural and optical properties. Furthermore, frequency and bias voltage evolution of dielectric and electrical parameters were analyzed using impedance spec-troscopy (IS) for all samples at room temperature (RT). Fluctuating and self-consistent results were ob-tained in the Ultraviolet-visible (UV) spectrum of the samples. The conductivity mechanisms were de-termined by calculating the s parameters of all samples for different regions. The complex impedance, capacitance, phase angles, dielectric constant, tangent factor, electric modulus, and frequency variation of ionic conductivity for the rosehip seed loaded hydrogel were successfully analyzed in detail using IS in the broadband frequency range. The increase in ionic conductivity of the RS-doped hydrogel with in-creasing frequency was attributed to its ability to exhibit the Langevin equivalent of Brownian motion in viscoelastic fluids, surface/bulk Maxwellian stress relaxation behavior, and the validity of the Stokes -Einstein relationship in biological fluids. In particular, the capacitive effect observed as a result of the Cole-Cole diagrams of the dielectric constant adapting to Smith Chat and the equivalent RC circuit al-lowed the material to be used as a capacitor.
