Abstract:

Polymer systems synthesized and studied as rf attenuators include linear polyenes, xanthene polymers, polybenzimidazoles, polyacrylonitriles, polyphenyleneaminoquinones, and polythiosemicarbazides. Metal chelate polymers synthesized and studied as rf attenuators include polythiourea-copper complexes and polythiosemicarbazidecopper complexes. Metal doped polymers were also prepared and studied during the course of the work. Physical measurements to characterize these polymer systems include volume resistivity measurements on pressed samples as a function of temperature, impedance and attenuation measurements on pressed coaxial samples as a function of frequency and electron paramagnetic resonance spectra measured on powdered samples. General results of the program indicated very low attenuation constants, though the metal chelate polymers show some promise for development. However, carrier mobility in these materials severely limits their conductivity. Author
