Abstract
With the noticeable growing rate of electronics, materials with good flexibility and high conductivity that can provide electromagnetic interference (EMI) shielding with minimal thickness are urgently needed. Here, for the first time, we demonstrate the potential of a non-woven composite film with unique core-shell and sandwich combined microstructure for EMI shielding. A 0.27-mm-thick reduced graphene oxide coated Fe3O4@SiO2@polypyrrole (FSPG) composite film exhibited an average EMI shielding effectiveness of 32 dB (specific EMI shielding effectiveness can be ∼ 12,608.4 dB cm2 g−1). This performance originates from the relative high electrical conductivity of FSPG films (0.71 S/cm) and multiple internal reflections from the interconnected core-shell and sandwich microstructure in the free-standing films. The mechanical flexibility offered by the FSPG films enable them to be considered as a new alternative material with efficient EMI shielding.
