Polyaniline/graphite nanosheet, polyaniline/Ag/graphite nanosheet, polyaniline/Ni/graphite nanosheet composites and their electromagnetic properties

The polyaniline/graphite nanosheets (PANI/NanoG), polyaniline/silver plating graphite nanosheets (PANI/Ag-NanoG) and polyaniline/nickel plating graphite nanosheets (PANI/Ni-NanoG) composites have been synthesized. The three kinds of polyaniline/graphite nanosheets composites were characterized by X-ray diffraction techniques (XRD), Fourier transform infrared (FT-IR) and scanning electron microscopy (SEM). Results showed that the kinds of composites had synthesized successfully. The resulting PANI/graphite composites exhibited both electrical and magnetic loss at the microwave frequency of 8.2-12.8 GHz. The electrical loss, was 3.52 at 10.5 GHz. the magnetic loss, was 2.52 at 9.5 GHz and the total loss was 5.58 at 10.5 GHz for PANI/NanoG composites; the electrical loss was 5.4 at 10.6 GHz, the magnetic loss was 1.34 at 9.6 GHz and the total loss was 6.9 at 11.0 GHz for PANI/Ag-NanoG composites; the electrical loss was 4.3 at 10.7 GHz, the magnetic loss was 4.4 at 9.33 GHz and the total loss was 7.2 at 8.2-12.4 GHz for PANI/Ni-NanoG composites.
