Enhanced EMI shielding efficiency using carbon, graphite, and polyaniline blends

Abstract [en]

Conducting polymers have found significant applications in the past decade in industrial, scientific, and medical (ISM) fields. The characteristic features of conducting polymers like reversible proton doping, variable conductivity, facile synthesis, and low cost make them potential candidates in various microelectronic applications. Conventional microwave absorbing materials such as carbon and graphite in the powder form were blended with polyaniline as base at different proportions and microwave properties such as transmission, reflection, and shielding efficiency (SE) were evaluated from S parameter measurements using HP 8714ET network analyzer. The newly developed polyaniline blend exhibits high-electromagnetic interference shielding efficiency when compared with previously developed materials and is a promising candidate for shielding applications.
