Poly(3,4‐ethylenedioxythiophene)/poly(4‐styrene sulfonate) (PEDOT/PSS) films hybridized with halloysite nanotubes (HNTs) were for the first time investigated for electromagnetic interference (EMI) shielding. The hybridization of the HNTs induced EMI properties for the pristine PEDOT/PSS films, and the content of the HNTs in the hybrid films significantly influenced the EMI properties of the hybrid films. The highest EMI shielding effectiveness of the hybrid film is −16.3 dB in the measured frequency range from 2 to 13 GHz for the PEDOT/PSS film hybridized with 75% HNTs, using a sample with 4.5 mm thick. The contribution of EMI shielding effectiveness in the hybrid films is mainly due to dielectric loss rather than magnetic loss. © 2016 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2016 , 133 , 44242.
