dc.description.abstract	Gold nanoparticles (AuNPs) of about 5 nm diameter were biosynthesized at room temperature using HAuCl4 as the precursor and green tea leaves extract as the reducing agent. The PVA/ KH2PO4 (KDP) composite film showed percolative behaviour around 2.5wt% KDP. Interestingly, addition of 0.05 wt% of AuNPs to the PVA/2.5wt%KDP percolative composite film (with percolation threshold of 2.5 wt% KDP) destroys percolative behaviour of this composite film. Furthermore, the PVA/2.5wt% KDP/0.05wt% AuNPs nanocomposite film exhibited high room temperature dielectric permittivity ( '  ). High value of '  of the films promises direct application in capacitors	en
