“Background Researches regarding polymer-metal and polymer-inorganic multicomponent hybrid composites such as polyaniline/silver (PANI/Ag), poly(ethylene oxide)/aurum (PEO/Au), PANI/Fe3O4, etc.

have attracted much attention during the last two decades due to their large potential applications in the fields of electromagnetic interference (EMI) shielding [1–3], AMP deaminase energy storage devices [4–6], catalysis [7–9], and sensors [10–14]. These hybrid composites show better chemical and physical properties than bulk materials. Among various polymers, PANI as a versatile conducting polymer is usually selected to compound with noble metals or inorganic particles owing to its easy preparation, anticorrosion, and the low cost of raw material. Recently, Kamchi et al. [3] have elaborated serials of camphor-doped PANI/FeNi nanoparticle-based EMI shielding composites. The maximum conductivity value of 104 S m-1 and the shielding effectiveness (SE) of 90 dB of the prepared multilayer composites have been detected over the frequency band of 8 to 18 GHz. Leyva et al.
