synthesis and characterization of poly(aniline-co-carbazole)@fe3o4 magnetic nanocomposite for x-band microwave shielding application

A novel conductive nanocomposite system of poly(aniline-co-carbazole)@fe3o4 was sucsessfully synthesised and dispersed in polydimethyl siloxane (pdms) matrix to be used as an effective flexible electromagnetic shield in the x-band microwave frequencies. the results from the vector network analizer reveal that the reflection absorption mechanisem is the dominant. shielding efficiency up to 12% was measured due to charge transformation between the conductive polymer chain and magnetic nanoparticle interface.
