A novel green approach for the construction of conductive glass fiber‐silver‐PANI ternary composites with efficient electromagnetic interference shielding and excellent thermal stability

Abstract

AbstractThe study proposes a novel way of amalgamating three different materials to develop an effective electromagnetic interference (EMI) shielding material by completely utilizing the distinct properties of each one. First and foremost, binary composites have been prepared by combining with various weight of silver (1, 2, and 3 g) and constant weight percentages of glass fiber. The synthesis of the glass fiber‐silver‐PANI ternary composite is then brought about by PANI particles precisely encased on the surface of the glass fiber‐silver binary composite. The intertwining of a thin PANI coating on the binary composite is done successfully via simple in‐situ polymerization of aniline using lime juice as the dopant. The structural properties have been studied with XRD and FT‐IR. The SEM analysis reveals the effectual distribution of PANI on binary composite. The thermal stability of the composites has been studied using TG analysis. Most importantly, the glass fiber‐silver‐PANI ternary composite shows significantly high EMI shielding effectiveness up to 41 dB in the x‐band region.
