This chapter gives a brief oversight of the preparation, characterization, and electromagnetic interference shielding studies of conducting polymer and MWCNT composites. The different approaches have been implemented to fabricate composites, which are used as EMI shielding materials. The key emphasis has been given to PEDOT conducting polymer, which is synthesized via emulsion polymerization. The topographical and chemical analyses of polymer composite samples were characterized by scanning electron microscopy, transmission electron microscopy, Fourier transform infrared spectroscopy, X-ray diffraction, thermo gravimetric analysis, and Raman spectroscopy. The dielectric and electromagnetic shielding measurements of the polymer composites were conducted by a vector network analyzer. In addition, PEDOT/MWCNT coated polyurethane foam usage as an antistatic material has also been discussed in this chapter.

Keywords: Anti-static, Electromagnetic shielding and dielectric measurements, Emulsion polymerization, Fourier transform infrared spectroscopy, Multi-walled carbon nanotube, Poly (3, 4-ethylene dioxythiophene), Scanning electron microscopy, Thermogravimetric analysis, Transmission electron microscopy, Xray diffraction.
