Carbon based Nano fillers polymer nanocomposites are the advance polymer materials used in electrical device applications. Among them carbon nanofibers are highly preferred because of their high aspect ratio, long fiber range, high contact surface area, higher electrical conduction with uniform dispersion property. In the present work we have developed a thin (PVDF-CNF) conductive polymer nanocomposite by solvent casting technique. Here we have focused on understating the dispersion effect on electrical conductivity and for electromagnetic interference (EMI). The developed conductive polymer nanocomposite showed uniform dispersion with higher conductivity and higher dielectric properties. The newly developed composite has significant applications in the field of sensor and shielding.
