Polymer Conducting Nanocomposite Film to Improve Electromagnetic Compatibility of Electronic Devices

This article presents the analysis of polymer conducting nanocomposites (PCNC) to improve the electromagnetic compatibility of various electronic equipment. PCNC has been fabricated using the reduced graphine oxide (rGo) as a filler, and poly (vinylidene fluoride-cotrifluoroethylene) [P(VDF-TrFE)] polymer as insulating polymer matrix. Simplest and efficient method of solution casting was used for fabrication purpose. The obtained nanocomposite films were characterized for surface structure using Scanning Electron Microscopy (SEM) technique. The dielectric parameters were obtained in the frequency region of 10KHz to 1MHz accordingly the shielding effectiveness was calculated using the dielectric parameters. The developed sheets are cost effective, flexible and showing excellent EMI shielding properties around 30dB for shielding of various electronic equipment to enhance their electromagnetic compatibility
