Abstract

The rapid advancement in wireless communication technologies has necessitated the development of advanced materials with tailored dielectric properties. Polymer materials, because of their flexibility, lightweight nature, and processing ease, are currently being used in initiatives to formulate low-dielectric materials specifically tailored for microwave communication applications. In the current investigation, the authors concentrate on the synthesis, characterization, and dielectric properties of five distinct novel polymer materials. The synthesized polymers are characterized utilizing Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and dielectric analysis. The FTIR spectroscopic studies elucidate the intricate interactions within the polymer materials of varied compositions, while the XRD spectroscopic patterns of all synthesized polymer materials exhibit an amorphous nature. Furthermore, the dielectric permittivity and loss tangent of the materials are assessed by employing a DAK probe across a range of temperatures. From XRD and FTIR, it is confirmed that the incorporation and interaction of the dopants within the polymer matrix occurred, indicating good compatibility and homogeneity in studied polymers. The dielectric measurements revealed that the doping significantly influenced the dielectric constant and loss tangent, making it possible to tailor the material properties for specific microwave frequency requirements. Results are compared with the body of the data available with the literature.

Keywords: Dielectric constant, FTIR, loss tangent, permittivity, XRD.
