Poly-N-vinylcarbazole-polyaniline (PANI) composites were synthesized using different loading concentration of aniline (0 025-0 1 M) for their microwave absorption characteristics The obtained composites were studied by Fourier transform infrared spectroscopy, thermogravimetric analysis technique, and atomic force microscope for their chemical structure, thermal stability, and the surface modifications, respectively The conductivity increased much with the increase of aniline concentration in the composites The composite sheets exhibited a strong microwave absorption in the microwave range of 1-10 GHz and achieved a maximum absorption value of 33 dB The position of absorbing peak shows a mixed trend moving from lower to higher and again to lower with an increasing the concentration of aniline in the poly-N-vinylcarbazole-PANI The new polymer composite exhibited an appreciable electromagnetic interference shielding efficiency compared with the previously reported PANI composites POLYM ENG SCI, 51 54-61, 2011 (C) 2010 Society of Plastics Engineers
