aniline in the presence of MMT with ammonium persulfate (APS) and hydrochloric acid (HCl) as oxidant
and acid dopant, respectively. PANI/MMT composites on structural properties were analyzed by FT-IR,
XRD and SEM. The result of FT-IR analysis signified an interaction between PANI backbones and MMT
layer surfaces. X-ray diffraction showed an increase in the interlayer spacing of MMT, signifying PANI
was intercalated into the MMT galleries. PANI prepared in the presence of MMT exhibited flake-like
morphology rather than granular particle form of PANI without MMT. PANI/MMT10% showed higher
electrical conductivity than pristine PANI. PANI and PANI/MMT were separately used as the fillers to
prepare paraffin composites and PANI/MMT10% had a better microwave absorbing performance than
PANI. The minimum reflection loss of PANI/MMT10%/paraffin composites with thickness of 8.0 mm
were -37 dB at 14.8 GHz and the effective absorption band under -10 dB was from 13 to 16 GHz.},
