Abstract
The dielectric and EMI shielding behaviors of styrene acrylonitrile (SAN)/polyaniline (PANI) polymer blends are investigated using impedance analyzer. The incorporation of PANI forms the phase separated morphology in SAN matrix and by increasing the concentration of PANI, the interconnected network of PANI phase develops within the SAN matrix. Near the percolation threshold concentration, the dielectric constant (\(\varepsilon^{\prime }\)) and dielectric loss (\(\varepsilon^{\prime\prime}\)) of SAN/PANI blends are enhanced up to five and eight orders of magnitude at 1 kHz, respectively. Moreover, total shielding efficiency (SET) was determined in the radio frequency range. SAN/PANI polymer blends show the total shielding efficiency at very less thickness of about 150 µm. Overall, shielding efficiency in SAN/PANI blends is improved owing to the increased number of charge dipoles accumulation at the insulator-conductor interfaces.
