| Özet |
| The development of multifunctional polymer nanocomposites with tunable electrical properties is vital for next-generation flexible electronics applications. In this study, we present a systematic investigation into the effects of graphene content on the dielectric, morphological, mechanical, and thermal properties of thermoplastic polyurethane (TPU) nanocomposites. Comprehensive characterization was performed using scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR), tensile testing, thermogravimetric analysis (TGA), and frequency-dependent dielectric and impedance measurements. TPU films with varying graphene contents (0%, 3%, 5%, 7%, and 10%) were fabricated via solvent casting. The results show that adding more graphene increases the interfacial polarization and helps form conductive pathways in the TPU matrix. At higher graphene concentrations, dielectric and … |
