摘要：
Hybrids of Polyaniline-Single walled carbon nanotube (PANI-SWCNT) nanocomposites were synthesized by in situ polymerization and are embedded in the polyvinyl alcohol (PVA) matrix to form nanocomposite films. X-ray diffraction technique (XRD), Fourier transform infrared spectroscopy (FTIR), and Field Emission Scanning Electron Microscopy (FESEM) were used to study structural and morphological properties which confirm the phase formation, characteristic infrared spectrum and surface morphology of the prepared films. Electrical, dielectric and electromagnetic properties were analyzed and found to enhance with increase of SWCNT in the films. The 3 wt% SWCNT loading film showed the highest AC conductivity with 18.37 x 10(-5) S m(-1) and maximum shielding effectiveness of 22.73 dB in X-band (8.2-12.4 GHz) region, among all other samples.
