| Özet |
| This study examines the dielectric, electrical, and impedance properties of thermoplastic polyurethane (TPU) composites enhanced with activated carbon (AC) at concentrations ranging from 0 to 10% over a frequency range of 1 kHz to 10 MHz. The analysis includes capacitance, dielectric permittivity (ε′, ε′′), loss tangent (tanδ), alternating current conductivity (σac), electric modulus (M′, M′′), and impedance spectroscopy (Z, R, X, θ) to assess charge transport, polarization effects, and relaxation behavior. Results show that increasing AC content enhances interfacial polarization and charge mobility, improving dielectric performance and influencing conductivity mechanisms. Among the investigated composites, AC7 achieved the best balance of properties, with a dielectric constant of 54.47 at 10 kHz, an ac conductivity of 0.0169 μS/cm, and a loss tangent of 0.054 at the same frequency.
