“…Polyvinylchloride is 3rd most used produced polymer in the world, Polyaniline and graphene nano platelets are relatively new materials having excellent set of properties and currently being used various applications. Various researchers used either one or combinations of any of these two materials and characterize them for EMI shielding applications [1][2][3][4][5][9][10][11][12][13][14][15][16][17][18][19][20]. The above studies discovered that such systems yield electrically conductive system, providing a huge possibility that can be used for various applications.…”

Polymer nano composites based on poly vinyl chloride matrix were fabricated using polyaniline (PANI) and graphene nano platelets (GNP) as electrically conductive nano filler for the application of electromagnetic interference (EMI) shielding. DC conductivity was first evaluated by using cyclic voltammetry and found an increasing trend of electrical conductivity as PANI and GNP was added in PVC matrix that confirms the formation of electrically conductive network structure. Dielectric properties like dielectric constant, dielectric loss and AC conductivity were evaluated in frequency range of 100 Hz to 3 MHz that gives basic prediction for EMI shielding effectiveness. Vector Network Analyzer (VNA) was used to assess EMI shielding properties using coaxial cable method in 11GHz to 20GHz range and it was found that a maximum of 29 dB shielding was archived with the incorporation of 15 wt% of PANI in PVC. This value increased to 56 dB as 5 wt% GNP added in PVC/PANI 15 wt% blend. Interaction of matrix with filler, nature of filler and dispersion of filler in matrix are the key parameters for achieving high shielding effectiveness.
