Abstrakt: Polyaniline is a conductive polymer that possesses a high attenuation level, making it suitable for electromagnetic interference shielding applications. In this work, a film of emeraldine phase polyaniline was synthesized, and its microwave absorbing properties were studied. The polyaniline was prepared using the oxidative polymerization method. A Fourier transform infrared spectrometer and an X-ray diffractometer were employed to confirm the formation of the emeraldine salt polyaniline. A scanning electron microscope showed flaky particles of the as-prepared polyaniline. The microwave absorption test carried out on a vector network analyzer showed a remarkable response in the frequency range from 9.5 GHz to 11.4 GHz, with the highest reflection loss value of -15.6 dB reached at 10.1 GHz. This result shows the potential for polyaniline applications to be developed for X-band absorber materials. [ABSTRACT FROM AUTHOR]
