Nowadays, emerging research in the areas of conducting polymer-based metal oxide composites have shown much interest among modern physical and chemical researchers due to their unique absorption properties. In the present work, the conducting polyaniline/ molybdenum trioxide nanoparticles blended in DBSA was synthesized by in-situ polymerization technique with varied weight % (10, 20, 30, 40 and 50) of molybdenum trioxide. The analysis on the EMI Shielding Effectiveness (EMI-SE) of the synthesized samples in the X-band frequencies (8.2-12.4 GHz) is presented here. The influence of molybdenum trioxide nanoparticle in Polyaniline/DBSA matrix over the EMI-SE has been studied. It is observed that the synthesized composites exhibit excellent shielding efficiency in the entire range of X-band. The absorption governed shielding effectiveness of the synthesized polyaniline/DBSA/MoO3 composite finds cost effective applications and manifests electromagnetic compatibility in the X-band frequencies.
