A high-performance electromagnetic interference shielding (EMI) material is a solution to this issue. This study introduces a cost-effective one-pot synthesis method for polypyrrole/silver (Ppy/Ag), polypyrrole/graphene (Ppy/Gr) and polypyrrole/silver/graphene (Ppy/Ag/Gr) ternary composites with adjustable graphene concentrations. Detailed structural and morphological analyses using FTIR, XRD and STEM confirm the successful incorporation of Ag nanoparticles and graphene into the polypyrrole matrix. The total shielding effectiveness (SET) of the ternary composites in the Ku band shows an impressive 30.86 dB at 12.7 GHz for the 5 wt.% graphene composite, primarily driven by absorption mechanisms (SEA&gt; SER). The synergistic interaction between Ag, which provides conductive pathways, and graphene, which offers structural reinforcement, significantly enhances interfacial polarisation and conductivity, surpassing the performance of binary counterparts (Ppy/Ag and Ppy/Gr. The results of this work introduce a lightweight, potent and economical composite material for EMI shielding applications in the Ku band. 2025 Elsevier B.V.
