Polymer nanocomposites were prepared by in situ polymerization of aniline with graphite oxide (GO), gamma-Fe2O3, and BaTiO3 as electromagnetic interference (EMI) shielding materials. GO, gamma-Fe2O3, and BaTiO3 nanoparticles were incorporated in the nanocomposites to improve the electromagnetic properties. The nanocomposites showed the significant improvement in both EMI shielding efficiency (SE) and thermal property due to the thermal conductivity of GO, the magnetic effect of gamma-Fe2O3, and the electric effect of BaTiO3. The EMI SE of nanocomposites was improved due to the synergetic effect of reflection and absorption of electromagnetic interference by GO, gamma-Fe2O3, and BaTiO3 additives.
