In the present study we have developed a graphene film using vacuum infiltration technique and evaluated its Electromagnetic interference shielding effectiveness (EMISE). Multi walled carbon nanotubes were prepared using chemical vapor deposition technique and graphene was prepared by thermal exfoliation of graphite oxide. We also compared the EMISE of graphene thin film with carbon nanotube film. Electrical conductivity of the MWCNTs film and graphene films were measured with four probe technique in order to avoid contact resistance.
