Zusammenfassung:Polyaniline (PANI) and Graphene Nano Sheets (GNS) composite material has an application in electromagnetic interference (EMI) shielding. The verified EMI Shielding PANI/GNS composite material re-prepared to analyse the optical behaviour in UV and Visible region. The nanocomposites characterized by SEM, XRD and FTIR. Present study involved four samples of 0%, 1%, 3% and 5% GNS in PANI to form composite and characterized by UV Visible. Optical properties in an UV-Visible region have been investigated with Tauc method to find direct band and indirect band gap. Also, the Localized defect states are observed using Urbach Energy plot.
