Dielectric Analysis of PVDF-CNF Conductive Polymer Nanocomposite for EMI Shielding Application
Keywords:
Conductivity, Dielectric, Electromagnetic Shielding, Polymer NanocompositeAbstract
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.
