Abstract

The main objective of this work is to develop a conducting composite film for coating of various electronic
devices to provide effective electromagnetic interference (EMI) shielding for various applications. Here we
present and analyse the dielectric properties of Polyvinylidene fluoride (PVDF) and graphite (Gr) composites in
radio frequency ranges (100 KHz-10MHz). The PVDF-Gr composites were prepared by solvent casting method.
The PVDF-Gr composite films exhibited high dielectric properties at a certain addition of graphite in radio
frequency regions. The main advantage of these composite incorporates their light weight, flexibility and low
cost. The EMI shielding properties of the PVDF-Gr composites was evaluated theoretically using ɛ′, tan δ, and σ
in the radio frequency region
