Abstract

In this work, excellent electromagnetic interference (EMI) shielding using a ternary blend of Poly(3,4-ethylenedioxythiophene) Polystyrene sulfonate (PEDOT: PSS) is demonstrated. Electromagnetic interference shielding of up to 26 dB in the X-band (8.2-12.4 GHz) and 28 dB in Ku-band (12.4-18GHz) is achieved. The ternary blend being PEDOT: PSS-PEO-PVA in the ratio of 85:7.5:7.5 wherein PEDOT: PSS is a conducting polymer widely known for its high conductivity with atmospheric stability. The drop casted ternary blend film measured thickness of 42±2 μm. The EMI shielding measurements are further repeated in the interval of 30 days, and the values are observed to be unaltered. Thus, this PEDOT: PSS blend study elucidates the EMI shielding properties along with effective shielding stability.
