Abstract

Polypyrrole (Ppy) nanoparticles were synthesized by surfactant directed chemical oxidation method. The synthesis of Ppy nanoparticles were confirmed by Fourier transform infrared spectroscopy and transmission electron microscopy. The prepared samples were tested for electromagnetic interference (EMI) shielding. It has been observed that the particle size of the Ppy nanoparticles decreases (53, 42, 28 nm) while the dc conductivity (3, 7,22 S/cm) and total shielding effectiveness (23, 46, 49 dB) increases with surfactant concentration for the Ppy samples (P1, P2, and P3).
